For some time, I've been noticing that the deadlines on NF tasks doesn't match their arrival time. For example, I've just received

19/12/2013 10:14:54 | NumberFields@home | Scheduler request completed: got 1 new tasks
19/12/2013 10:14:56 | NumberFields@home | Started download of sf2_DS-24x13_Grp342305of819200.dat
19/12/2013 10:14:57 | NumberFields@home | Finished download of sf2_DS-24x13_Grp342305of819200.dat

which matches task 5508893:

Sent 19 Dec 2013, 10:20:43 UTC
deadline 29 Dec 2013, 10:20:43 UTC

The difference is almost 6 minutes - my computer clock seems to be accurate to within 10 seconds, after checking the BBC and a few internet time sources.

Not an urgent issue, but next time the server needs maintenance, it might be worth hooking it up to an NTP time server.

Edit - for confirmation, I clicked 'OK' on the above post at 10:32:30 local.

Hi Richard,

Thanks for pointing that out. I will look into fixing that on the server.

An ntp server has been implemented and appears to be working.
