Hi William,
Devin answered already and although I haven't tested it, I believe
his solution is the most straighforward one.
If you want a more general solution, you run into a bug, which causes
Revolution to return times, which are one hour off. The bug is said
to be fixed, as you can read here <http://quality.runrev.com/qacenter/
show_bug.cgi?id=2387> but date calculations are still far from
straightforward in Revolution. Maybe we should re-open that bug report?
The following is an attempt to provide a function that calculates
time differences regardless of platform. Unfortunately, it fails
miserable on Windows, if time difference is less than an hour. Also,
I am not sure what the effect of daytime savings is. In theory, it
should work, but it doesn't. I didn't test this on Linux yet.
-- this script does not always work correctly!
function clockTimeDif theTime1,theTime2,theFormat
set the useSystemDate to true
if theFormat is empty then put "short time" into theFormat
if not (theFormat contains "sec") then
-- correct for rev bug
put the time into myTime
convert myTime to long internet time
put char -2 to -1 of myTime into myZoneM
put char -4 to -3 of myTime into myZoneH
put myZoneM * 60 + myZoneH * 60^2 into myBug
-- another bug in Windows? DST?
if the platform is "Win32" then
subtract 60^2 from myBug
end if
else put 0 into myBug
-- convert and subtract
convert theTime1 from short time to seconds
convert theTime2 from short time to seconds
put (theTime1 - theTime2 - myBug) into myDif
-- convert
do "convert myDif from seconds to" && theFormat
-- done
return myDif
end clockTimeDif
end clockTimeDif
Why can't we just convert time to seconds, do the calculation and
convert back the result to a time format? Shouldn't this be simple?
Best regards,
Mark Schonewille

Hi there all,
I am subtracting some numbers and that is working ok with the
following code:
put value (field "xt" - field "y") into fld "z"
What If I want to use clock times like: 07.30 (seven thirty in the
morning) ?
When I subract '16.00 - 07.30' I get '8.7' and I want it to be '08.30'
So now Rev sees these numbers as decimal numbers.
What code need I put in there to make it work?
greetings,
William de Smet
