take the form of a Unicode string formatted as: "YYYYMMDDThhmmss.s". In this

representation, YYYY shall be replaced by the year, MM replaced by the month (01-12),

DD replaced by the day (01-31), T is a constant character 'T' delimiting time from date,

hh is replaced by the hour (00-23), mm is replaced by the minute (00-59), and ss by the
|

second (00-59). The ".s" is optional, and represents tenths of a second.
