Subject:      'Pre' survey taken after 'Post' survey - syntax help

Hello,

I have a large dataset that contains data from 2 timepoints.  The data for
the pre timepoint came from an online survey that was taken at the
participant's convenience.  The data for the post time point came from a
survey given during a program offered on several dates (the dates of this
program spanned 2 months).  My problem is that some participants completed
the web survey (the pre timepoint) AFTER attending the program.  Thus, some
completed the pre after completing the post.  The timestamp for my pre data
is in a dd-mmm-yyyy date format (ie 2-6-2005) and the timestamp for my post
data is in a m/dd/yyyy h:mm:ss string format (ie 7/10/2005 4:21:37 PM).

I need to change the format of one of the timestamps so that they match
each other in format.  I also need help writing syntax that will create a
varaible that is equal to 1 if the timestamp for pre came after the
timestamp for post.  Can anyone help me?
