Re: [HTCondor-users] Do not run jobs during work hours

Being in the corporate, rather than the academic world, I would probably need about six signatures to disclose my code even though it's very similar to page 356 of the 3.4.9 manual, but some of it is pretty obvious:

IsNighttime = ( ! IsDaytime )
IsWeekend = ( ! IsWeekday )
IsBusinessHours = ( IsDaytime && IsWeekday )
IsAfterHours = ( ! IsBusinessHours )

:D :D

These become machine attributes via startd_attrs, so that users can do this for their large, non-urgent runs:

Requirements = TARGET.IsWeekend

My main excursion from the manual's text, aside from separating the day and time attributes, is the situation of having to handle when the nighttime overlaps midnight GMT - in Eastern time, GMT+5 or +4 (or points west), if you have your Nighttime start at 8pm in the summer and 7pm in winter, that translates to ClockMin == 60 in the UTC system time zone from November to March and ClockMin == 0 from March through October, so you need two clauses for daytime and nighttime unlike one as Dennis showed in his GMT+1/+2 Netherlands time zone or the example in the manual.

If you don't have your system time zone set to UTC, and you don't mind having two syslog entries at 2:30am an hour apart once per year, and a 1:59am log entry immediately followed by a 3:00am log entry once per year, then you can avoid that extra ClassAd logic to handle when the night end time is less than its start time.

I'd like to do the same. Can you give the code yu used to  set up STARTD_ATTRS for IsWeekday, IsDaytime, and IsBusinessHours? Thanks.
