Raising for second time (original post disappeared).

1) All events within the Zoho Project Calendar have moved forward by 2 days - past, present, and future.  All events once due Monday are now on a Tuesday, Tuesdays are Thursdays, etc. etc. etc. and so on and so forth.  This occurred over the weekend when no one was using the system. 

Is this a known issue?  Is there a work around or do I have to manually move everything (a year and half of events) back?

2) In addition to this, the forward arrow for months no longer works.  Backwards is fine and clicking on the month allows travel, but the forward does nothing.
