TimeZone difference while retrieving Datetime field

Hi,

When i am retrieving CRM Datetime field(in C#) when it is having 12 AM, means 0:00 then i am getting one hour previous time. If it is not 12 AM then i m getting correct time. If i am adding time zone bias then the problem is solving for 12AM, but except this time remaining all i am getting problem.  If any one knows please let me know what is the problem.

Thanks,

Sravan J
