not started to work on ST3 mac os x

[webresh]

Hi!
Thanks for a nice plugin.
I just installed it on Sublime Text 3 running on Mac OS X and when hitting F5 all I see is notice in status bar:
[InsertDate] Error parsing format string

in console I see
[InsertDate] Error parsing format string
UnknownTimeZoneError: "Parameter 'tz_out' = 'EST' is not a valid timezone name"

What to do to start using plugin?

Please enter from InsertDate import pytz; pytz.timezone('EST') in the console and paste the output here.

[webresh]

from InsertDate import pytz; pytz.timezone('EST')
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "pytz in /Users/1/Library/Application Support/Sublime Text 3/Installed Packages/InsertDate.sublime-package", line 188, in timezone
InsertDate.pytz.exceptions.UnknownTimeZoneError: 'EST'

[FichteFoll]

Hm, okay. Can you try from InsertDate import pytz; pytz.all_timezones_set ?

Edit: I think I found the problem.

[webresh]

sure,
it responded
set()

then I hit F5 and again

[InsertDate] Error parsing format string
UnknownTimeZoneError: "Parameter 'tz_out' = 'EST' is not a valid timezone
name"

Thanks for the report, fixed in 0.5.4 (should be out on package control within 15min).
