RegEx for ShortTime string

Hi Experts,

The following regular expression validates the times in the format: "11:47AM" .... How to I change it to validate "11:47 AM" (The space is important because it needs to be in DateTime.ToShortTimeString format.

Thanks,

^([1-9]|1[0-2]|0[1-9]){1}(:[0-5][0-9][aApP][mM]){1}$

If the space is required

if the space is optional

ozo: I'd suggest using the ? sign instead of the asterisk. This way you ensure only one space is entered, and not more.

Agreed, assuming "11:47  AM" should be rejected.
