Comment (by Viper007Bond):

 Replying to [comment:3 Viper007Bond]:
 > This bug should be avoidable if we stop determining GMT (UTC) date/time
 based on local date/time when creating a post '''without''' a provided
 date/time. Since those values will default to now, we don't need to
 convert timezones because we know what now is in UTC. We can determine now
 in UTC and local time independently of each other.

 Note that this doesn't fix `get_gmt_from_date()` (I'm not sure that's
 possible), but it does fix trying to publish a post now and having it end
 up being scheduled an hour in the future.
