Re: [lang] StopWatch enhancement

Good questions. The returns are strings.

The biggest problem with StopWatch and the other time classes is working out
exactly how they should work and inter-relate, particularly re formats
(everybody has their own favorite).
And interestingly, its not entirely obvious to me as to what the getXxx
methods return - is it a string or a number? Whats the format? How is
localization dealt with? ((see also joda.sourceforge.net))

If interested, in my own timer class, I have these extra format/output
options that I wouldn't mind adding to StopWatch:
getMinutesWithMilliSeconds
getMinutesWithSeconds
getMinutes
getSeconds
getSecondsWithMilliSeconds
getMilliSeconds
which should be self explanatory.

I tried out the StopWatch class as pointed out to me by Stephen and I
added an extra toString method for a different format option. The
extra option is:
0hrs 0mins 0secs 0ms.
Add if desired :-)
