Fine, but that's a lot longer than ntpdate needs.  In addition, it
will keep trying to establish contact, which can be undesirable.
ntpdate is the obvious choice for a dialup connection; you can put it
in the linkup script and it will set the date even before you know
you're connected.

Right, this issue has nothing to do with ntp.  Check your
/etc/localtime file.  It should be a copy of your local time zone file
in the /usr/share/zoneinfo hierarchy.
