DHCP Lease time notation (Timezone) wrong



  • 2.1-RELEASE (i386)
    built on Wed Sep 11 18:16:22 EDT 2013
    FreeBSD 8.3-RELEASE-p11

    My timezone is set correctly in General Setup.

    Whenever I enable the "Change DHCP display lease time from UTC to local time." option all times go wrong. When I disable it they're correct after restarting DHCPd. So the setting is backwards.

    Exactly as outlined in this (old) thread: http://forum.pfsense.org/index.php?topic=51580.0

    Can someone correct the description on the configuration panel for the next release? I bet it would save a few people (like me) a bit of confusion ;).



  • The bad behaviour in 2.1-RELEASE is actually:
    a) Box not checked -> do not adjust the times read from the lease file, the lease file now happens to contain time in local, so times display in local.
    b) Box checked -> local time zone offset is added to the time that is thought to be in UTC from the leases file, but actually is already local time. Effectively moving the time further away from UTC. e.g. time zone offset is +02:00 then if the lease file says 08:00, that is already in local time in the leases file, the UTC equivalent is really 06:00, but the code adds another +02:00 and reports 10:00.
    This pull request fixes the behaviour to match the description on the GUI: https://github.com/pfsense/pfsense/pull/864
    After fix:
    a) Box not checked -> local time is read from the leases file, time zone offset is subtracted to get UTC, UTC is displayed.
    b) Box is checked -> local time is read from the leases file and displayed as-is.



  • Hmmm if I interpret your post correctly that would indeed fix it :)

    When will this go into a release? (estimate)



  • I posted in the Development forum to see what the plans are for 2.1.1, as I am interested myself anyway - http://forum.pfsense.org/index.php/topic,70508.0.html



  • Right, lets continue there :)

    Thanks for your replies so far.
