    Output
 timetm
    Time component of the binary timestamp, expressing local time.
 tns
    Nanoseconds since time component of the binary timestamp.
 inacctm
    Seconds of inaccuracy component of the binary timestamp. If the
    inaccuracy is finite, then tm_mday returns a value of -1 and tm_
    mon and tm_year return values of zero. The field tm_yday contains
    the inaccuracy in days. If the inaccuracy is infinite, all tm
    structure fields return values of -1.
 ins
    Nanoseconds of inaccuracy component of the binary timestamp. If
    the inaccuracy is infinite, ins returns a value of -1.
