Trying to allow visitors to my radio show website to display our broadcast schedule in the timezone of their own choosing. But I’m having trouble finding a way to do the conversion. We don’t store exact dates for the show (i.e. Saturday, Feb. 4, 2012 at 2 p.m.), just days of the week (i.e. Saturday at 2 p.m.).
I know the Pear Date object can do lots of manipulation of dates, but it seems to only operate on specific dates.
You can see our schedule at www.floydianslip.com.
