man cron:

       It is possible to use different time zones for crontables.  See
       crontab(5) for more information.


man 5 crontab:

       The CRON_TZ variable specifies the time zone specific for the
       cron table.  The user should enter a time according to the
       specified time zone into the table.  The time used for writing
       into a log file is taken from the local time zone, where the
       daemon is running.


I guess you could run a (perl) script that changes CRON_TZ in your cron
table(s) whenever you change the time zone you're in.  Or you could run
a script that changes the times in the entries.  Since the docstrings
say that cron either uses inotify or checks the tables every minute, I
would think that you're not limited to 'crontab -e' for modifying the
tables.
