Run git builds on schedule

Fixes #1079. Using 17 08,15 * * * as a schedule:

At minute 17 past hour 8 and 15

Assuming our staff stick closer to the standard 9-5 most of the time, would running a 2nd CRON job just after 17:00 not be more suitable?

Just curious.

Times seem pretty arbitrary, some comments for why would be good

[erri120]

UTC (office and @Sewer56)	@erri120 and @Al12rs	@halgari
08:17	09:17	02:17
15:17	16:17	09:17

I picked the minutes arbitrary, it's considered "good practice" to pick something at random that isn't exactly 0, 15, 30, or 45 because everyone else runs their CI at that time.

I picked the hours 08 and 15 because it's before most of our start and end times. The idea is that we'd be able to fix any issues without going into overtime.

We could technically further limit the schedule to only run on work days.

Yeah, we should do that.
Running before active hours makes sense as it is guaranteed to get the latest stuff from the previous day.
I wouldn't mind moving the other build to before standup, so 14:17 UTC or a bit sooner, as we often have meetings after that and having a build to test the changes of the morning could be useful.

Updated to 17 08,14 * * 1-4:

At minute 17 past hour 8 and 14 on every day-of-week from Monday through Thursday

My train of thought was the exact same when I made the suggestion.

• From what I heard, most of office starts at 9.00am
• We work 8 hours per day, not 7 (4x8 in our contracts)
• Thus most of office should be clocking out at 17:00

I commented, because I thought the end time was actually set too early, rather than too late.
But yeah, standup and morning works for me.
