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
