My requirement is as follows:
I want a text box which will accept CSV values and the values can be any time of a day, ie. in one text box I can enter multiple clock times separated by comma. Hour and Minutes will be separated by a colon, Seconds not required.

If a.m. or p.m. can be associated it would be great [0-12 basis], otherwise 0-24 basis will be fine.

Accepted Inputs: 1:00, 12:45, 23:59, 11:34
Thanks in advance.

But I need to combine them.
Got the answer from ASP.Net forum,here it is:
Time Input : 1:00 AM, 12:45pm,03:59am,11:34 aM, ...
RegEx : (([0]?[1-9]|[0-1][0-2]):([0-5][0-9])( )?(AM|am|aM|Am|PM|pm|pM|Pm))+((,)( )?(([0]?[1-9]|[0-1][0-2]):([0-5][0-9])( )?(AM|am|aM|Am|PM|pm|pM|Pm))+)*
Time Input : 1:15,15:45, 23:59,00:34, 02:05
RegEx : (([0]?[0-9]|[1][0-9]|[2][0-3]):([0-5][0-9]))+((,)( )?(([0]?[0-9]|[1][0-9]|[2][0-3]):([0-5][0-9]))+)*
Time Input : 1:15,03:59am,15:45, 23:59,00:34, 11:34 aM,02:05, 1:00 AM, 12:45pm
RegEx : ((([0]?[1-9]|[0-1][0-2]):([0-5][0-9])( )?(AM|am|aM|Am|PM|pm|pM|Pm))|(([0]?[0-9]|[1][0-9]|[2][0-3]):([0-5][0-9])))+((,)( )?((([0]?[1-9]|[0-1][0-2]):([0-5][0-9])( )?(AM|am|aM|Am|PM|pm|pM|Pm))|(([0]?[0-9]|[1][0-9]|[2][0-3]):([0-5][0-9])))+)*
