Unfortunately that is usually the opposite way we typically do things, and sometimes challenging especially if there are hundreds of rows of data. I believe the trick is to preformat the field before you put data in it. The following may give you a start down that path. If you need to time in fractions of a second the macro will need to be a bit more complicated. You will have to modify his example a tiny bit but I think you will get the idea. You can just use a mouse click to input the time. Press your Ctrl key combo to insert the time into the active cell.Īlso, checkout this Mr. Set the Ctrl key combination you want to use to execute the macro In Visual Basic Editor (VBE) select the menu Insert then Module.Ĭopy and paste the following subroutine into the VBE Module You colud make a macro and assign a hot key to it. I rather suspect intervals are required here, in which case I’d suggest storing the data as an integer, using the smallest time granule required (perhaps milliseconds), with appropriate formatting for display purposes. By leveraging double float you can achieve sub-seconds to an accuracy of 3 milliseconds but you’d stray beyond supported behaviour and as a punishment you’d have to write your own revised temporal functionality.įurther consider that the sole temporal data type in the product is designed for ‘timestamp’ data i.e. To get back to the original question, I’d suggest that temporal functionality in Excel and VBA is accurate only to one second granularity. BTW why doesn’t the DATEDIF function support hours/minutes/seconds? (to which the official answer of course is, What DATEDIF function?) yyyy-mm-dd hh:nn:ss, then I think you’ll find the result is zero. +TIME(0, 144, 0), formatting the cells using an appropriate date format e.g. If, instead of using +0.1, you repeat your steps using temporal functionality e.g. The point here is that Excel relies on the format of the cell to identify a date. Tushar Mehta Said: “Microsoft made a very bad design decision when it implemented time as a fraction… Try this simple test….” There doesn’t seem to be a trade-off here that I can see (other than coding time by developers). If a user enters fractions of seconds, display fractions of seconds.
It seems rather easy for Microsoft to have done this differently. I don’t know of any way to get the hundredths to display in the formula bar. To change the cell from 3 hundredths to 3 tenths, follow these steps: F2 to edit the cell, backspace three times to remove the AM and the preceding space, type. Into the cell, which contains no hundredths. If you were to edit the cell, say, by pressing F2 and Enter you lose the hundredths. The hundredths are still stored, but they aren’t displayed in the formula bar. The noteworthy aspect of this example is that there are no hundredths in the formula bar. Like an over-protective mother, it shields you from the harsh realities. Usually the formula bar will tell you the truth regardless of how you’ve formatted the cells, but not in the case of dates and times. Excel attempts to bridge that gap by displaying dates and times as dates and times rather than these cryptic numbers. What it’s not good for is understandability by most humans.
This method is great for adding, subtracting, and generally doing other math operations on dates. It’s only 8:00AM and already a third of the day is gone. While dates are integers, times of day are the fractions between the integers. Similarly, times are stored as fractions of a day. That means that 0 is stored as 1 and 04-March-2007 is stored as 39,145. As you probably already know, dates are stored as the number of days from a particular date, usually 3. I should say that they are a strange beast because they are the same thing. I’m not sure that I know this answer definitively, but I’ll tell you what I think based on what I see.ĭates and times are strange beasts in Excel. Is this a common occurrence in excel or is there something that I am doing wrong or should be pressing? This will have a massive impact on the results that I am looking at. When I click in the cell, the value rounds up or down depending so 1:23.30 will round to 1:23.00. However, if I make a mistake inputting the data e.g type 1:23.03 when it should be 1:23.30 something weird happens. I am a rowing coach and am putting the data that my crew gives me from their training sessions into a spreadsheet in the mm:ss.00 format.
