Minor Description
Jim Larus reports:
In the schema for the DB, the timezone in the PERSON class is a 25-char string, while the timezone field in SOCIALEVENT is 100-char string. Some of the timezones in includes/timezones.html are longer than 25 char, so I suspect the latter is correct.
Both the php and rails schema use a 25-char string in PERSON, where as the Java app uses 255 (which is probably an overkill). Only the PHP app has timezone in the SOCIALEVENT table - the other two apps don't.
