Time Zone Offset Calculation?

Apr 2, 2014

I've got a CSV file that has been sent to me where each entry has a vehicle reports in with certain metrics. Included in these metrics are the time the metric is reported. The problem I am having is that the time is delivered in UTC date/time (in Column A). Column B has an "offset" to show how many hours difference there are between the UTC time and the local time for that particular vehicle.

Problem 1 - My initial thought was to use "Text to Columns" with space as the delimiter, thinking I could just run a simple subtraction formula once completed. The problem here is that if an entry is recorded after 7pm local time, the UTC time moves into the next day, and the simple subtraction formula will not take that into account.

Problem 2 - Even if there was a workaround, it seems that the numbers in the "Offset" column don't work well with time calculations because they are not a time (it's -5, -6, -7, or -8).

Change Date Time Zone

Feb 15, 2009

I receive from my broker in the States a financial report that shows transaction dates in American EST. As I'm in Australia this is somewhat annoying. Is there a way, perhaps adding an extra column, that converts this time to Australian Eastern Standard Time?

Creating A Time Zone Userform

Jul 29, 2008

I would like to add something to my workbook which, when called, gives you current time in Tokyo, Australia, USA, London, Europe (for example).

I am trying to work out what would be best.

Would it be possible to create this on the Status bar?

Alternatively, i guess a Userform shown as modeless (but i am not sure if the controls holding the times will update.

Time Zone Conversion - Morning Or Night Shift

May 6, 2014

I have this Spreadsheet that has different country, Is it possible that it will auto convert the time into PHT Time (GMT +8) which is in Column A.

For example:

Its 3PM (Cell G1) in Bhutan. I want it to be converted in GMT +8
So therefore the time for GMT+8 will be 5PM and will be shown in Cell A1.

Also there will be an automated identifier in Column B that will identify if that time is for morning shift or night shift.

The morning shift is 12PM til 8PM
While the night shift is 8PM til 11AM.

to say -

If (Offset 0 rows and 3 columns from AL13 = "Gross" then =SUM((OFFSET(INPUT!$A$1,12+AL6,2)+OFFSET(INPUT!$A$1,13+AL6,2))/AL5) otherwise 0)

Calculation On Offset From Cells Within Date Range?

Dec 17, 2013

I have some data A2:A1000 where there is a start date in column D and end date in column E (formatted DDMMMYYYY). In column F I have a formula that calculates the NETWORKDAYS between the dates.

What I want is a set of formulae that will look in column D for a date between 01/01/2013 and 31/01/2013 (or any date I specify) and find the 'MIN', 'MAX' and 'AVG' of the values in column F where the date in column D matches my criteria.

What I can't figure out is how to offset from the cells matching the date range!?

Time Calculation (Spanning Dates And Using Military Time)

Jul 15, 2014

I have 4 distinct columns.

Adm Date Adm Time Trans Date Trans Time
1/16/2014 937 1/16/2014 1045
1/1/2014 121 1/1/2014 121
1/14/2014 800 1/11/2014 735
1/30/2014 100 1/30/2014 205
1/13/2014 800 1/12/2014 1202

I would like to calculate the difference (# hours spanned from the dates shown). Unfortunately when we transfer the data the COLON is dropped from MILITARY TIME so I am having problems in the calculation. This is also made more difficult as some of the calculates span over two dates.

Adding A Time Offset Based On Time Of Day

Oct 1, 2008

I am replicating a Matlab program which calculates tide levels at different times of day. I need to replicate it in excel to speed up data analysis and I am nearly there.

what happens is I need to apply a time offset to the time of high tide at port a based on the time of day, so if it is:

between 00:00 and 06:00 the high tide at port b is 81.6 minutes after the peak at port a
between 06:00 and 12:00 the high tide at port b is 74.56 minutes after the peak at port a
between 12:00 and 18:00 the high tide at port b is 81.75 minutes after the peak at port a
between 06:00 and 12:00 the high tide at port b is 79minutes after the peak at port a

I tried this formula, where CO2 has the time/date of the high tide at port a:
=IF(CO2<0.75,IF(CO2<0.5,IF(CO2<0.25,CL2+(81.6/(24*60)),CL2+(74.56/24*60)),CL2+(81.75/(24*60))),CL2+(79/(24*60)))

The problem is the high tide on 07/01/2005 07:45 is read as 38359.32 rather than 0.32 - is there any easy way to tell excel I'm only interested in the time not the date? I have this spreadsheet setup now to do all the other bits required and i is just the timing that is a problem.

Calculation On Time

Mar 1, 2009

I have been burning brain cells trying to figure this out.
I get these numbers from an online source and they come in like this:

A B C D E
1/1/0912:01AM02:40AM11:18AM07:55PM

The times do not come in as times...when I format the cell to time it doesnt change...that is my first problem.

What I would need to do to these times is: take B and C and find what time is in the middle of them and put that in a different column.

This mess will also need to be plotted on a chart with time by the minute for one day as the X axis. In my example I drew lines on the chart to show what I mean....the blue lines I dont want charted...I use those to find the time in the middle.

Same Time Calculation

Feb 5, 2009

I am trying to get a total column that will give the total only when two particular devices are down at the same time. This total will be taken from a long list of downtime entries for different devices but I only want the total when two particular devices are down, for example

Devicedatedowntimedateuptimetotal time
102/01/0911:00:0002/01/0911:09:0000:09:00
202/01/0911:00:0002/01/0911:04:0000:04:00
202/01/0902/01/09
103/01/0903/01/09
303/01/0903/01/09
604/01/0904/01/09
204/01/0913:09:0004/01/0913:12:0000:03:00
104/01/0913:02:0004/01/0913:15:0000:13:00
505/02/0905/02/09
total 1/200:07:00

In the example I am just wanting to work out the total time when both device 1 and 2 were down at the same time, above the total would be 7 minutes because for 4 minutes on the 2/1/9 and 3 minutes on the 4/1/9 they were down at the same time.

Time Calculation ...

Jun 4, 2009

Having been looking round this site for quite some time now and always finding what I needed I am now a registered member who needs your expertise.

I have a spreadsheet for which I need to calculate hours worked depending on a few criteria.

[data] ...

The criteria is that Sat/Eve is 8pm to 6am weekdays and midnight to midnight on a saturday. Sun is midnight to midnight on a sunday, BH is a bank holiday and basic is everthing else. What I want to know is it these columns can be populated automatically using formulas.

I would really appreciate it if someone out there is up to completing this challange, as I have to manually populate this at the moment and it can be 5000+ lines long (it takes hours). If i need to change the layout it's not a problem, whatever it takes to automate it has got to be worth the effort.

Time Calculation

Apr 21, 2007

I have a time card sheet that I want to make automatically calculate the time I have worked. It is set up with four columns that can't be changed. The first column is "Time In(TI)", second column "Time Out(TO)", Third column "Time Taken For Lunch(TTFL)", and Finally "Hours Worked". I have no problem getting the formula to calculate the difference in "Time In" and "Time Out" but taking the 30 minutes out of that is causing a rift. If I put the 30 minutes in 00:30:00 format it will take it but it thinks it's 12:30:00 and it displays in 00:30:00 which I want it to display 30. Just to clarify, I am using =(TI-TO)-TTFL in the Hours Worked cell.

How Do I Reduce Calculation Time

Sep 12, 2008

I am a big fan of huge files (30MB+) all interlinked with array formulas ...and lots of them. The problem is...one calculation take literally 5 hours. (I have one file I try to calculate since cca 4 hours now...it's at 63%)

I keep getting extra memory with no visible improvement on the processing time. Is there a trick out there that I can use? Something is clearly wrong.

I feel I will soon have to give up Excel, or my formulas, or my job ...

Formatting With Time Calculation

Oct 15, 2009

I have a calculation whereby I use two variables which are 1. Man hours left in the week formatted as [hh] and 2. Amount of work left to do in the week formatted as 0" Man Hrs" I need to carry out a calc which says:- Man hours left in the week - Amount of work left to do in the week.

The answer should tell me if I have a deficit or surplus of hours which can then use for planning purposes. Unfortunately the problem I have is that I can't make the formatting the same for both unless someone knows of a workaround.

Man hours left in the week = 128. Man hours required to complete all work this week = 224. Therefore I need to say 128-224 = -96. However when I do this this an answer of 16 is returned.

Variable Time Calculation

Dec 12, 2007

[code] ......

=SUMIF($A:$A,">="&TODAY()-1,D:D)-SUMIF($A:$A,">"&TODAY(),D:D) calculates the total in Col D looking back from today. The results gives you 12:00. What I need is a formula that will look back from the current time to 24 hours in the past, NOT 1 day, to calculate the total in Col D. Looking back 24 hours, from 10:00am, the results would be 6:00.

Since the first time on 12/12 has not arrive, it will not calculate it, but will look back from 10:00am on 12/12 to 10:00am on 12/11 and calculate a result of 6:00 hours.

Calculation Of Time Formula

Jul 14, 2009

I am trying to calculate the response time between when a phone call comes into my workplace and when the responder calls back...I have created a formula that does this using the times and dates of when the calls were recieved and went back out. This works except when the call comes in on one day and goes back later in the day the next day, making the response time larger than 24 hours. I also have it set up to eliminate 15 and a half hours from the calculation because our place of business is not open during this time. Further details....

The formula currently being used is... =IF(G50=E50, H50-F50+(H50

Time Spent Calculation

Feb 3, 2010

I need to find out the total time an issue was 'open' (not resolved) during business hours. Issues come in and resolution time is based off of a priority. Priority 1 should be resolved in one hour, Priority 2 should be resolved in 4 hours, Priority 3 should be resolved in 1 business day (8 hrs), Priority 4 should be resolved in 2 business days (16 hrs), Priority 5 should be resolved in 5 business days (40 hrs), Priority 6 should be resolved in 10 business days (80 hours).

I have start dates/times field in a column (mm/dd/yyyy hh:mm) , a resolution dates/times field in another column (mm/dd/yyyy hh:mm) and a priority in another column (1-6). I need to calculate the time an issue is in open status (not resolved) based on it's priority but I need for it to take into consideration business hours (Monday thru Friday...7 am to 7 pm)...and not calculate time outside of 'business hours'.

Textbox Time Calculation

Oct 26, 2006

I'm attempting to calculate the total number of hours between a start time and end time using textboxes on a Userform.

Here is my latest attempt:

Private Sub D24_Exit(ByVal Cancel As MSForms.ReturnBoolean)
Dim myvalue As String
Dim myhour As String
Dim myminutes As String

myvalue = D24.Value

Select Case Len(D24)
Case 1
myhour = "0" & Mid(myvalue, 1, 1)
myminutes = "00"
Case 2
myhour = Mid(myvalue, 1, 2)
myminutes = "00"
Case 3

The above codes are an attempt to force an entry as time (7, 07, 700, 0700=7:00 / 13, 1300=13:00 etc.). However, the result is not correct.

For example:
Start Time in Textbox(D24)=07:00
End Time in Textbox(D25)=17:30
Result in Textbox(D27)=0.4375
Desired Result in Textbox(D27)=10.5

I've never calculated times in textboxes,

Calculation Time And Charge Rates

Oct 8, 2007

I am trying to figure out a formula to figure out how much to charge for hrs of a rental. There is an automatic $1000 charge regardless of time used. the rate chart is as follows:

$1000 + hourly charge = total

=<50 hrs= $15/hr
>50hrs but <100hrs= $6.50/hr
>100hrs=$4.10/hr

ex: so is A1= 200hrs then i want B1 to equal $1820.($1000 + (200 x 4.1))=1820.

I have an idea on how to write the formula, but i am having a little bit of trouble with it.
