Question

i have a machine set in GMT.
i would like to have a cron task scheduled from 6AM to 5PM in PST, which is GMT-8.

gmt time zone. typical.

00 06-17 * * * 

now -8 produces a crontab bad hour error.

00 22-09 * * *

the following is accepted or should i say, no error.

00 22,23,0,1,2,3,4,5,6,7,8,9 * * *

any short form therefore?

Answer 1

For vixie cron,

Lists and ranges are allowed to co-exist in the same field. “1-3,7-9” would be rejected by AT&T or BSD cron — they want to see “1-3” or “7,8,9” ONLY

That is, the following:

00 22-23,0-9 * * *
