sql server twine date conversion

i wish modify twine this:

'10/15/2008 10:06:32 pm'

into homogeneous datetime value sql server.

in oracle, i contend this:

to_date('10/15/2008 10:06:32 pm','mm/dd/yyyy hh:mi:ss am')

implies i contingency parse twine , following modify controlling those codes. seems ridiculous such paltry operation. there an easier way?
