Dear Srinivas Nayak,

I don't suppose you're writing to a network mounted disk, with the 
network device's clock about half a second behind your test machine?  
Otherwise -- and I'm just guessing here, and will leave it to you to 
UTSL -- this could be explained by use of two different algorithms for 
converting a higher-resolution time source to the one-second 
resolution.  A truncation algorithm versus a rounding algorithm could 
produce the result you demonstrate.

Regards,

David
