I perfectly agree that being able to specify the time zone of the time isn't the solution to the DST switching problem, but nonetheless important, imo. As a practical example: I want to mirror some larger MPEG weather satellite movies from a specific FTP server. They are released on a time specified in UTC (they really are, I checked). If it weren't for my pleasure only, I'd want to make sure I try to fetch them at the exact time, and not one hour late. I probably would opt for being able to specify a time zone completely in the syntax,adding an optional field, or making cron obey TZ= in the cron table.
