Date rounding shouldn't be too confusing...
I think new users are likely to be familiar with the time and localtime
commands, or at least have them in the camel book.  If a new date class is
created, users will have to depend on the perldocs for that new class,
which may be a little harded.  If the plan is to go the object route,
at least there are good ones around that could probably be reused, such as
DateTime::Precise which has some nice parsing.
