    Re: 0000 not 2400?
    From: Paul Hirose
    Date: 2004 Oct 18, 22:04 -0700

    The ISO 8601 notation for date and time allows both 0000 and 2400:
    
    "The end of one day (2400) coincides with 0000 at the start of the
    next day, e.g., 2400 on 1985 April 12 is the same as 0000 on 1985
    April 13. If there is no association with a date or time-interval,
    both represent the same clock time in the 24-hour timekeeping system."
    
    Normally you would only use 2400 to express the end of a time
    interval. E.g., "The system will be down for maintenance from 2100 to
    2400."
