class CFPropertyList::CFDate

This class holds Time values. While Apple uses seconds since 2001, the rest of the world uses seconds since 1970. So if you access value directly, you get the Time class. If you access via #get_value you either geht the timestamp or the Apple timestamp

Constants

DATE_DIFF_APPLE_UNIX
TIMESTAMP_APPLE
TIMESTAMP_UNIX
