Re: TimeZone trouble

Cairo does this too.  I used to use midnight local time to determine 
what 'day' it is.  That would mean the application would fail for an 
hour in some timezones.  I changed to using some other time...  23:58 I 
think.  This might fail somewhere too, but nowhere I have found.
