6 years ago I don't think this is actually a problem because date.today() is timezone naive so it should get the date from the system clock. The real problem would come from the fact that all users share every Week object, so if multiple users access the site from separate timezones, specifically at the beginning or end of the week, different weeks could be set as "present" every time someone accesses the schedule page.
Timezones cause an issue at the transition between weeks as some timezones will experience the transition of the current week early and some late. A quick fix was added but nothing robust. Timezones should factor in to determining when a week is current or not.
