36# The International Earth Rotation Service periodically uses leap seconds
37# to keep UTC to within 0.9 s of UT1
38# (which measures the true angular orientation of the earth in space); see
39# Terry J Quinn, The BIPM and the accurate measure of time,
40# Proc IEEE 79, 7 (July 1991), 894-905 <http://dx.doi.org/10.1109/5.84965>.
41# There were no leap seconds before 1972, because the official mechanism
42# accounting for the discrepancy between atomic time and the earth's rotation
43# did not exist until the early 1970s.
44
45# The correction (+ or -) is made at the given time, so lines
46# will typically look like:
47#	Leap	YEAR	MON	DAY	23:59:60	+	R/S
48# or
49#	Leap	YEAR	MON	DAY	23:59:59	-	R/S
50
51# If the leapsecond is Rolling (R) the given time is local time.
52# If the leapsecond is Stationary (S) the given time is UTC.
