Normalize the time component of the date. One idea is to use 12 PM GMT as a constant time, since then the date will be the same date everywhere in the world - except in New Zealand, Fiji, Kiribati, Samoa, & other states in the GMT+12/13 neighborhood, so you'll have to translate for them. iCal does this when synchronizing calendar dates.
