Add quarter day to current timestamp

[deepa.y]

Hi,
I have a requirement to add quarter day to the current timestamp
if current timestamp is 2/28/2012 10:32:17 PM,
my output should be 2/28/12 10:32 PM+(1/4)=2/29/12 4:32 AM
Please suggest me hoe can i achieve this?

Add 21600 seconds to the timestamp.

The function is called something like TimestampFromSecondsSince().
