[PermissionsEx] Group Lifetime problems

I am having serious issues with permissions ex right now with timed groups.
I run the following command:
/pex user Weasel_Squeezer group add vip empire 60

This should put me into the vip group for 60 seconds, but instead, it puts me in there indefinitely... I am still in the group after many minutes has passed. I looked at the permissions file for my entry under users, and the lifetime option has been added correctly as such:

Code:

Weasel_Squeezer:
  group:
    - Ruins
  worlds:
    empire:
      group:
        - Vip
      options:
        group-Vip-until: '1361051524'

I tried running some code to figure out exactly what that value is in relation too, but I found nothing. I do not think it is a timestamp because System.currentTimeMillis() subtracted by this or the other way around gives either a largely negative number or a positive number which when converted from milliseconds to days gives no accurate result, and even from seconds to days gives nothing like it should.

I also want to know why when you run the command again, it doesn't seem to add any time in the permissions.yml file. I want to have it so that it will add the time to the current time left for the player.

I may end up adding timed groups to my plugin instead...

Any ideas of whats wrong? this is extremely frustrating. I am going to explode.

 

Yes, it's correct value. User stay in vip group until next login. Sorry for my english.
