Weird problem for TIMESTAMP feild

[Tariq Murtaza]

Hi All,
I am getting very weired problem after shifting our server. here is the 
details:-

I have a table with two columns
   1-TimeStamp timestamp(14)
   2- SID bigint(20)
when inserting  _INSERT INTO _/_TABLENAME values (1258975462,125987)_ 
results in /_INSERT INTO _/_TABLENAME values (0000000000,125987)_
Timestamp entry gets zeros.

Any idea? whats happening....
Regards,
*TM*
