You should be able to use the date pattern "MM/dd/yyyy
hh:mm a" to add the AM/PM to your date. That's wild
that the date selector doesn't use seconds. Two
possibilities come to mind:
-sleep for a minute after generating the timestamp. :(
-use ant-contrib's <outofdate> task to set a
comma-delimited list of out-of-date target files into
a property, to be used as the includes attribute of a
<fileset>.
In Ant, two things that would also make sense:
-Add a format attribute to the date selector,
defaulting to the current one.
-Add a millis attribute to <tstamp>, incompatible with
its pattern attribute.
