To read timestamp from a line

I have a situation like, I have to read only the timestamp value from a line.
ex: Date and Time : 2013-05-11 12:12:34 MST

I cut the 'Date and Time' but unable to remove MST part.
I need a script to use in Datastage job.

can you guys help me with that

Thanks in advance

First of all, please don't hijack thread.
