Curious, it works for me. This program: | main | | define l_start, l_end datetime year to fraction(3) | define l_diff interval day to fraction(3) | | let l_start = current | sleep 5 | let l_end = current | let l_diff = l_end - l_start | | display l_diff | | end main display this: | 0 00:00:05.009

suppose I want to find time difference for two variables expressed as year to fraction , say l_start and l_end (l_diff is also the same type) if I say l_start = current sleep 5 l_end = current l_diff = l_end - l-start l_diff when displayed shows all zeros, I'd like to say 5 seconds (or whatever) any ideas?

And your way works for me, thanks, it was lack of interval definition Paul Roberts <proberts@lynx.informix.com> wrote in message news:7ovajn$hcs1@webint.na.informix.com... > In article <7ov9th$dv1@newsstand.cit.cornell.edu>, > Respectful <please_reply@newsgroup.com> wrote: > >suppose I want to find time difference for two variables expressed as year > >to fraction , say l_start and l_end (l_diff is also the same type) > > > >if I say > > > >l_start = current > >sleep 5 > >l_end = current > >l_diff = l_end - l-start > > > >l_diff when displayed shows all zeros, I'd like to say 5 seconds (or > >whatever) > > > >any ideas? > > Curious, it works for me.
