date ->advance: with=int, unit=[{second,minute,hour,day,week}]

Advance date object with the given amount of the specified unit. The default unit is second. Please note that larger units are omitted due to their unclear semantics. Units are converted to seconds. Given that the fields are in local time, creating a time from fields, date->advance and get the fields may yield strange results. For example:

?-	new(D, date(0, 0, 0, 30, 10, 2005)),
        send(D, advance, 1, day),
        get(D, string, string(Date))

Date = 'Sun Oct 30 23:00:00 2005'
