TBA time from iCal feed

Issue Summary

The school I work for uses HighSchoolSports.net for scheduling sporting events. I'm trying to bring in the individual calendars for each team. Problem - some games are parts of tournaments where the start time is determined by winning or losing the previous game, therefore a 'TBA' time. The feed brings the times in just fine using the ical parser except for the 'TBA' times. The DTSTART always ends up as UTC - 7 (I'm in the PDT) and since it defaults to midnight because there is no time set, the feed parser keeps giving it a time of 5pm the day before the event is set to occur. I'm certain it's actually because it misreads the timezone.

The 'TBA' events come with a DTSTART like this "DTSTART;TZID=America/Los_Angeles;VALUE=DATE:20110721"

I'm trying to get the php code to remove the ";VALUE=DATE" and then it should be fine. But I've tried doing this in the ical parser functions to no avail. Hoping to find a place in the Feeds code where this can be effectively done.
