Value Representation "Time"
A string of characters of the format hhmmss.frac;
where hh contains hours (range "00" - "23"),
mm contains minutes (range "00" - "59"), ss
contains seconds (range "00" - "59"), and
frac contains a fractional part of a second as small as 1
millionth of a second (range "000000" -
"999999"). A 24 hour clock is assumed. Midnight can be
represented by only "0000" since "2400" would
violate the hour range. The string may be padded with trailing
spaces. Leading and embedded spaces are not allowed. One or more
of the components mm, ss, or frac may be unspecified as long as
every component to the right of an unspecified component is also
unspecified. If frac is unspecified the preceding "."
may not be included. Frac shall be held to six decimal places or
less to ensure its format conforms to the ANSI HISPP MSDS Time
common data type.
Examples:
1. "070907.0705 "
represents a time of 7 hours, 9 minutes and 7.0705 seconds.
2. "1010" represents a time of 10 hours, and 10 minutes.
3. "021 " is an invalid value.
Notes
1. For reasons of
backward compatibility with versions of this standard prior to
V3.0, it is recommended that implementations also support a
string of characters of the format hh:mm:ss.frac for this VR.
2. See also DT VR in this table.
