When you display a time in a cell, Excel normally displays just the hours, minutes, and seconds. If you want to display When your macro is processing information in a worksheet, do you need to periodically make the contents of a cell bold? Enter your address and click "Subscribe.

Excel Date and Time - Everything you need to know

Simply do the subtraction as "a - b" or "b - a", whichever fits ones situation but wrap it with ABS so there is no negative involved. Elapsed time is the concern, not which direction it elapsed. Specifically, for the problem Dimitris describes, it cannot be a "real" negative since the ship is not able to unload before it docks So, since the result being "negative" or "positive" is simply an artifact of how one set up the calculation, and not the underlying reality, removing it from the result will not end up ruining the result.
Then the "dd:hh:mm" formatting is applied and always works, regardless of date system, since it is formatting a positive result. Lastly, if one has a strange situation in which, say for the problem below, the lay time has to be an elapsed time, but the ship has a day free, for unloading, say, and finishing earlier has to be recorded as a negative time finishes in 22 hours, was allowed 24 hours, so result has to be -2 hours , one can still do all the math as above modified to add the "free time for unloading" aspect , still wrapping that final result in ABS , including in an IF test to see if it was negative before the ABS was calculated by Excel, and output it as TEXT using the above format for times that exceeded the 24 hours, or adding a negative sign before the format for negative times.
Doesn't seem likely that last would usually be the case, because most instances of it would seem to have an element of stupidity to them in real life, those ships aren't getting paid by the port for unloading more quickly than the 24 hours Organizations though But mostly, it would seem the last paragraph would very seldomly be needed. Another last thought, about TEXT -ing the result. Bringing the result "back" to being a number, for further calculations, is problematic as Excel by itself, of nudged by TIMEVALUE , will bring it back as hours:minutes:seconds, not days:hours:minutes, so one would either need to consider that and disect the value for proper returning to a number, or perhaps simply redo the calculation ending with a number, before ABS , for the further work.
If one did that with a Named Range, that part could be readily available to both the main work AND the follow-on work. If it has to come back to being a number at all. Think it need a update. Hello Again Mr. Chris, The cell D44 contains the number dd:hh:mm The cell D45 contains the number dd:hh:mm So the cell D46 has the result dd:hh:mm When the cell D45 is greater than D44 I get in cell D46 When I use the format there is not ay problem in the final solution even D44 is greater or less the D But the problem has to do that using the form mess up other dates in the programme.
Hello Mr. Chris, Could you give me please a little bit clarification over the solution you proposed below. You mentioned : For example, turn your value into a number of hours, calculate, then convert back to dd:hh:mm. Zero will not matter and you can handle a meaningless negative sign however is needed. Say Dimitris, Since you are not actually calculating the difference between dates, you are processing an arithmetic expression. As with any engineering expression, simply make the units consistent and then change to whatever units you prefer when the calculation is complete.
For example, turn your value into a number of hours, calculate, then convert back to dd:hh:mm. Dear Mr. Andy Good Day, Thanks a lot for your prompt reply. I guessed that the format I used was uncommon, but due to professional reasons I would like to use that one. I followed what you wrote me but I got the below answer from the Excel after pressing the Enter button. The Lay Time is calculated in days, hours and minutes. There is nothing to do with a calendar month, for instance whether is January, February, etc.
Just it counts days, hours and minutes. For that reason I made that formula. Never Lay Time exceeds 31 days, at least as far as it concerned the today situation. I tried many times with the solution you proposed me, I also tried to use a single quotation mark but it didn't work.
I have a quantity of cargo, 33, MT and discharge rate is 8, per day. The numbers 33, and 8, are in different cells and don't enter in cells D44, D Submitted by Vadim Berezniker on December 2, - Vadim Berezniker's blog Log in to post comments reads.

Mac Forensics Tips and Tricks: The Epoch Converter Utility
Submitted by Vishal not verified on January 30, - Simply Great! The count begins at the "Unix Epoch" on January 1st, , so a Unix time stamp is simply the total seconds between any given date and the Unix Epoch. The formula evaluates like this:. The Excel date system starts on January 1, and counts forward. The table below shows the numeric values associated with a few random dates:.
Notice the last date includes a time as well. In order to see the value displayed as a time, a time format needs to be applied. The DATE function is useful for assembling dates that need to change dynamically based on other values in a worksheet.
