Difference in Time

My friend Mike (a.k.a The man from the other Side) who lives in Korat Thailand, just mailed me ''Hey Henkie, still 2 hours and 30 minutes to go''
I answered, ''for us 6 hours more in 2009''.
We will wait and see what will happen in 2010!!

P.s. Difference in Time in ''wintertime'' is 6 hours!!
Difference in Time in ''summertime'' 1s 5 hours!!
