 29.5 Combined date and time of day items
 ========================================
 
 The ISO 8601 date and time of day extended format consists of an ISO
 8601 date, a ‘T’ character separator, and an ISO 8601 time of day.  This
 format is also recognized if the ‘T’ is replaced by a space.
 
    In this format, the time of day should use 24-hour notation.
 Fractional seconds are allowed, with either comma or period preceding
 the fraction.  ISO 8601 fractional minutes and hours are not supported.
 Typically, hosts support nanosecond timestamp resolution; excess
 precision is silently discarded.
 
    Here are some examples:
