Why use regular expressions? Just split it into two pieces - the bit before the ":" and the bit after. Then make sure that the first bit is between 00 and 23 inclusive, and the second bit is between 00 and 59 inclusive.

i am not sure but i think regular expressions will work faster?
is it right??
Not necessarily. If you like you can use a regexp to ensure that what you've got is a pair of digits then a colon then a pair of digits, and at the same time capture those two pairs; that's reasonable.
But for checking that those pairs of digits are in the right range regular expressions are the wrong thing to use - not when you can just use "<=" and ">=" instead.
