Hi I'm running REXX script on ZOC terminal and i want to display current time and ETA like this:
start time 22:44:24
end time 22:56:24
but I don't know how to increment current time ???
maybe to convert time to seconds then increment it and then convert time in seconds back to hh:mm:ss ??
I tried this way but dont know how to convert back time from seconds
intTime= TIME('S')+900
say="start time " TIME()
say="end time " intTime
One way would be along the lines of:-
intTime = TIME('S') + 900
hours = (intTime % 3600) // 24
minutes = (intTime // 3600) % 60
seconds = intTime // 60
endtime = RIGHT(hours,2,'0') || ":" || RIGHT(minutes,2,'0') || ":" || RIGHT(seconds,2,'0')
NOTE!! I don't have access to test this and it's been many years since I've written Rexx or had access. However, I think the basic process would work. That is:-
1) Extract the hours as an integer from the time (catering for the the potential to cross into the next day or days ie the // 24 ()).
2) Extract the minutes, as an integer, from the time, after dropping/subtracting the hours (the remainder of the time divided by hours ie intTime // 3600).
3) Extract the seconds, as an integer, from the time. By obtaining the remaining of diving the time by 60 (will drop hours and minutes).
4) Building the end string as a concatenation of the hours, minutes and seconds. With : as the separator between two values (or surrounding the middle values). The right function to include a leading zero.
You could also try:-
intTime = TIME('S',TIME('S')+900,'S')
That is based upon TIME, which may be Object Rexx. I did also read something mentioning an extended TIME/DATE functionality. However, again that may have been referencing Object Rexx. Although, Mike Colishaw's name was mentioned.
Mike Colishaw, I believe, being the creator of the Rexx programming language.
