Time Of Day As Negative Decimal
Feb 6, 2012
Data from a SQL database represents time of day as a string of x's when imported into Excel. With CLEAN, I found that noon is -0.5.
This means that the calculation being used for noon is (24 * -0.5), or -12, meaning "go to the end of the 24 hour day, then go back half a day to noon." Similar calculations work other times of day.
Time entries that start in one day and end in the next are not allowed, so there is no problem with a change in day,
How can I convert this to the AM/PM time that my users need?

I need to convert regular time to decimal time. example regular time in A1
is 1:38 I need that number to be converted to decimal time = to 13:63. add
12 to the hour and divide 38 into 60 to get the minutes. Our time clock
prints on a 12 hour basis and I enter to excel in decimal time.

I've got a time difference from 8:00AM - 12:30PM as 4.30 I'm trying to get the minutes, .30, converted into a 6 minute increment, .5. Is it possible to do this and if so how would it be done? Below is a chart of how the time is converted from 6 minutes increments into decimal form.
6 = 0.1 36 = 0.6
12 = 0.2 42 = 0.7
18 = 0.3 48 = 0.8
24 = 0.4 54 = 0.9
30 = 0.5 60 = 1.0

I need to separate a list of times from a telecommunications bill. I have 170,000 line of data.
The Times are represented as below.
eg
46 46 Sec
59 59 Sec
100 1 Min
159 1 min 59 sec
200 2 mins
502 5 mins 2 sec
1256 12 mins 56 sec
3456 34 min 56 sec.
How do I separate them to a decimalized per min value.

i am tracking my working hours at night, so i type in the time i start and the time i quit like this:
A 1 start B 1 end
A 2 22:30 B 2 02:30
now i want to calculate the time between.
but since excel don't like the negative time i got a problem. i figure i must make a function something like
=IF(B2<A1,B2+24)
i have tried a few but i don't get the parameters right so i get errors,

I have a formula calculating time to the second (e.g HH:MM:SS). I am calculating the difference from the time something was scheduled to be done vs. when it was actually completed. What I can't get Excel to do is calculate the same time but listing the time in negative, as if the project went over and by how much.
I know how to do this in numbers view, but unable to do this in time view.

I’m trying to get the difference between times, BUT I want to account for “negative” time. So if I project that an employee will finish a task at 2 am, and they finished at 2:30 am, I want the result to be -:30, not just :30. If they finished at 1:30 then it would just be :30. Hence, my dilemma. I can get the difference, but didn't think Excel could recognize negative times. Right now I am using =MOD((A1-A2),1) or =(A1-A2+(A1<A2))*24/24 and in cells A1+A2 I am using military time.

I can't use 1904. I have a formula that almost works.
I am doing everything in Military time. This is the finial peice of the puzzle.
Our shift begins at 18:00 and ends up until 7:00 (am) or so depending onwork
A1 I have a time (Projected-Estimate of when all work should be done)
A2 I have a time (Actual- Time the work was actually complete.)
A3 Will be show the difference in either a Negative or Positive time.
Three Examples: (The first two work as is and are perfect) ....

I'm trying to make a shift schedule template, and it's all done except that i cant sum the hours the way I think i should be able to.
I've attached the file for reference.
I've added in some hours for myself as an example. I have 47.5 hours in the week. I've got 3 Rows, In Out and Hours. I've formatted the In and Out the way i want them, but I would like the Hours row formatted as a decimal, so that 7 hours 30 minutes would show up as 7.5.
I'm also having trouble with the totals column at the end. Although D8:J8 total 47.5 hours, it's adding them as 23:30.

(First please don't send me a link on how to subtract time or show Negative time. I know about 1904 ect.. I can't use that. I need a variation on the formula I am using if possible)
A1 I have a time
A2 I have a time
A3 I have a formula subtracting A2 from A1
The times will vary in A1 & A2. Sometimes A1 will be earlier or later thus giving me negative or positive times. I have a formula that will give me a correct answer but will always show either Positive or Neg depending on what I put in the last part of the formula "-H:MM or H::MM" =TEXT(MAX($A$1:$A$2)-MIN($A$1:$A$2),"-H::MM") in A3. I want it to do the subtraction but say if A1 is > than A2 then "-H::mm", If A1 is < A2 then "h::mm". I don't know if that is possibly or how to incorporate that into what I have.

It seems that time (i.e. -1:00) will be default as #########, etc. This makes me very unhappy. How to get around?
I could be fine with converting time to a total in seconds (i.e. 1:00 converted to 60 seconds)... but I'm not sure what kind of formula could do that.

the Times work fine 22:00pm to 5:30am or 6:00am to 5:30am
Formulas
J4
=IF(ISNUMBER(D4),(D4>E4)*MEDIAN(0,E4-N$4,O$4-N$4)+MAX(0,MIN(O$4,E4+(D4>E4))-MAX(N$4,D4))-F4-L4,0)
K4
=IF(ISNUMBER(D4),MAX(0,MOD(E4-D4,1)-J4-L4-M4-I4-F4),0)
L4
=IF(ISNUMBER(D4),IF(MOD(E4-D4,1)-F4>P$4,(MOD(D4+P$4,1)>E4)*MEDIAN(0,E4-N$4,O$4-N$4)+MAX(0,MIN(O$4,E4+(MOD(D4+P$4,1)>E4))-MAX(N$4,MOD(D4+P$4,1))),0),0)
M4
=IF(ISNUMBER(D4),MAX(MOD(E4-D4,1)-F4-I4-L4-P$4,0),0)
but if I try 22:00pm to 6:00am or later
The following is displayed
Negative Time in J4 and the wrong result in K4
this is not what I need
It should be showing the following
J4 2:00 K4 5:00 L4 00:00 M4 00:00

Many years ago I created a complicated spreadsheet that calculated employees's leave, sick, vacation etc. The timekeeper would indicate the amount(s) used for a particular day and it would automatically calcuate. The problem with this is that the time keepers do not use .25, .50, or .75 for the fractured time. Instead they used .15, .30 and .45. Previously, I used a convuluted if statement looking to the right of the leave to figure out what and how to calculate it and I'm trying to revamp it to make it more streamlined.

I trying to create a schedule on my 2002 excel. I placed all the times in HH:MM AM/PM format. But somehow...I don't know what I was doing...all the times instantly appear as decimals on the cells. The times I inputted still appears in the cell's formula bar. I tried changing the cell's format to my prefferred time format, but the cells wouldn't budge.

I'm building a schedule in excel and am having trouble with the calculation of total hours when lapsing a day, or more specific, adding it into my current equation. For example; Monday they clock in at 5pm and work till 1am. I have found a couple of ways to get the desired out come from this on it's own. I just add the value of a day if the out time is less than the in time, or if the out time minus the in time is less than 0.
However, I need to add this calculation into an equation that is already calculating time elapsed within a single day, turning that into a decimal number and then checking if the total time elapsed is less than 6 hours, if false it subtracts a thirty minute break. Here is the current equation I'm using, I'm sure that there is an if(or, or if(and I could use to make it work when the time lapses 12am while also performing the 6 hour check to subtract the break.
=IF(((F7-INT(D7))*24)-(D7-INT(F7))*24

formulae that converts % into time and visa-versa.
I.e 1.5 hrs = 1.30 hours ( i.e 90mins)
or the other way round
1.30 hours = 1.5 hrs..

I have devised a simple formula when a member of staff enters a date and time into a cell it starts deducting from todays date and time. ie:
Cell A1 - Date and time is entered by staff
Cell B1 - Is the above cell +24hrs
Cell C1 - NOW()
Cell D1 - B1-C1 Formatted in hours ( [h] :mm:ss (Like a count down clock)
The problem i have is that i cannot get Cell D1 to show minus ours it just goes to negative and shows continous #####. Is there any way i can get Cell D1 to show the hours it has gone minus by.

I have a problem with adding time values. The idea of my spreadsheet is to count time worked, and then calculate any variance from the normal shift length (i.e. 7h 30m). My formulas work fine until I work less than 7h 30m in a shift.
Example:
A1=start time
A2=end time
A3=IF(A2="","",MOD(A2-A1,1))
A4=IF(A3="","",(A3-(TIME(7,30,0))))
When the duration is over 7h 30m, A4 correctly returns the value of extra minutes. But when the duration is under 7h 30m the return is #####.
PS A1:A2 are formatted in a custom format hh:mm and A3:A4 are formatted as h:mm, and I'm using Win7 & MS Office 2010.
