[kronolith] Times off by 25 hours

[HiP-HiPpO]

I have several Horde/kronolith calendars available via subscription.   
I have tried several different client calendar apps, i.e. Mozilla  
Lightning and Andriod default calendar, and with each of them the  
calendar items that are pulled from the Horde/kronolith calendars end  
up on the client calendar app as 25 hours behind.

So an event on the Hoard calendar for Tuesday at 5pm is shown on the  
sync'ed client calendar app as Monday at 4pm.

Any tips?
