/// Convert a time expressed in seconds since Jan 1, 2000 into an 8-tuple which
/// contains: (year, month, mday, hour, minute, second, weekday, yearday)
/// If secs is not provided or None, then the current time from the RTC is used.
/// year includes the century (for example 2014)

/// mday    is 1-31
/// hour    is 0-23
/// minute  is 0-59
