TimeDiff Unable to Subtract Values
Keywords: TimeDiff Unable Subtract Values Time Imtestamp
Question:
I have a script that uses FileYmdHms to get a file timestamp and TimeYmdHms() to get the current time and then 'If TimeDiff(current, timestamp) > "0000:00:00:06:00:00"' to let me know if the file is over 6 hours old. I use the same script 8 consecutive times and also the same code in a number of other scripts. I very routinely get an error that TimeDiff can't subtract the values provided but never in the same script or iteration. Since I'm using functions to create the values I assume (dangerous as it may be) that they are creating valid date-time strings. Any thoughts on why it fails sometimes and not others and more importantly, how to correct it?Answer:
#DefineFunction udfTimeDiff (strYmdHms1, strYmdHms2)
; Make valid datetime strings.
strYmdHms1 = TimeAdd ("0000:1:1", strYmdHms1)
strYmdHms2 = TimeAdd ("0000:1:1", strYmdHms2)
; Compare datetime strings.
If strYmdHms1 > strYmdhms2 Then Return TimeDiff (strYmdHms1, strYmdhms2)
Return TimeDiff (strYmdHms2, strYmdhms1)
#EndFunction
; Test.
strYmdHms1 = "0:0:0:0:5:32" ; invalid date
strYmdHms2 = "0:0:0:0:3:10" ; invalid date
strYmdHmsDiff1 = udfTimeDiff (strYmdHms1, strYmdHms2) ; "0000:00:00:00:02:22"
strYmdHmsDiff2 = udfTimeDiff (strYmdHms2, strYmdHms1) ; "0000:00:00:00:02:22"
