I have the following Cron expression i use with Quartz.net:
0/5 * * ? * MON-FRI
Basically, every 5 seconds, Mondays - Fridays.
How can I modify this so it only runs between 7am and 8pm on those days?

I know Crontab != Quartz.net but they use the (mostly) the same notation for the timing stuff.

A:
This entry would be for every five minutes between 7:00 and 7:55 on Mon to Fri:
0/5 7 * * 1-5 who /usr/bin/what
as user who running /usr/bin/what. To my knowledge, cron does look inside a minute.
But you could start something at 7:00am on Mon to Fri which then itself would
do {
work
sleep(5) // or sleep(4) or whichever, depending on length of work task
} while (not yet 08:00am)
which is not that hard to put together.

Thanks for your help - In the end I came up with:0 0/5 7-20 ? * MON-FRIWhich is every 5 minutes (a little diff. from my initial request) but this works.

Oh, right, I missed the 8pm. If you want to run the last one at 20:55 then 7-20 for the hour field is indeed correct.
