Hai Roei Bar,

        This expression has a problem ..... that is .,The time format like 1:15 pm is accepted by this condition, which never accept. only 01:15 pm accept

accept             ---- 01:20 pm
never accept   ---- 1:20 pm

this is the problem.. Please help me to remove this problem
Thanks in advance..
