B4J Question Why no milliseconds support for jDateUtils PeriodBetween method?

[m4.s]

I'm trying to log, for code optimization and refactoring benefit, how long each of my application's subroutines take to process (i.e. between last and first code line).

Most subs execute in less than one second, but I'd to still like to know if one is taking 0.25 sec vs. 0.9 sec. As well as, say, if one's taking 1.7 or 4.34 seconds.

Seems my only option is to calculate difference between end and start times in ticks and format result to "ss.SS".

Would prefer, however, that the Period type just also returned a Milliseconds property...and am surprised it does not.

Calculate the difference between end and start times in ticks and you have the difference in milliseconds.
If you want seconds, just divide the difference by 1000.

I agree with klaus. Don't use DateUtils to calculate short intervals. DateUtils.PeriodBetween solves a very difficult problem.

Testing performance is much simpler:

Dim n As Long = DateTime.Now
'...do whatever you need
Log($"Took ${DateTime.Now - n}ms"$)
