The COMMENT statement is not absolutely required, but is highly
recommended to aid readability.
n
The year should always be the full four digits
(“
1991” is correct, but
“91” is not).
‘I’hls
is to avoid problems with the year 2000, when the
shortened version of the year will be “00.”
n
The hour value should be in 24-hour “military” time.
n
When writing a
CITIflle
and the fractional seconds value is zero, then
the “seconds” value may be printed either with or without a decimal
point: either “47.0” or “47” would be acceptable. When reading
a
CITIllle,
the seconds value should always be read as if it were a
floating point number.
