fix #1118
Use - %Z
not with -
use localized date/time format
Merge branch 'master' into now_with_tz
make dateutil a requirement, simplify date parsing by removing strptime, now it supports UTC-offset TZs in date field
Write correct timezone in new_post but there is something broken on the 'in the future' comparison
calculate offset to UTC correctly
Use minutes in TZ offset
Use the actual system TZ for current_time
fix #1161
use the new correct date formatting in tests, use UTC in tests
fixed test_scheduling
flake8
use actual 60-second minutes
Fix test_scheduling when used as part of the suite [tests are leaking locale]
removed dependency on pytz
flake8
simpler offset calculation using dateutil, actually pass the right tz
dateutil tz objects have no localize method
