+# @(#)leapseconds	8.1
+
+# Allowance for leapseconds added to each timezone file.
+
+# The International Earth Rotation Service periodically uses leap seconds
+# to keep UTC to within 0.9 s of UT1
+# (which measures the true angular orientation of the earth in space); see
+# Terry J Quinn, The BIPM and the accurate measure of time,
+# Proc IEEE 79, 7 (July 1991), 894-905.
+# There were no leap seconds before 1972, because the official mechanism
+# accounting for the discrepancy between atomic time and the earth's rotation
+# did not exist until the early 1970s.
+
+# The correction (+ or -) is made at the given time, so lines
+# will typically look like:
+#	Leap	YEAR	MON	DAY	23:59:60	+	R/S
+# or
+#	Leap	YEAR	MON	DAY	23:59:59	-	R/S
+
+# If the leapsecond is Rolling (R) the given time is local time
+# If the leapsecond is Stationary (S) the given time is UTC
+
+# Leap	YEAR	MONTH	DAY	HH:MM:SS	CORR	R/S

+#                                    UTC TIME STEP
+#                             on the 1st of January 2006
+#
+# A positive leap second will be introduced at the end of December 2005.
+# The sequence of dates of the UTC second markers will be:
+#
+#			2005 December 31,     23h 59m 59s
+#			2005 December 31,     23h 59m 60s
+#			2006 January   1,      0h  0m  0s
+#
+# The difference between UTC and the International Atomic Time TAI is:
+#
+# from 1999 January 1, 0h UTC, to 2006 January 1  0h UTC  : UTC-TAI = - 32s
+# from 2006 January 1, 0h UTC, until further notice       : UTC-TAI = - 33s
+#
+# Leap seconds can be introduced in UtC at the end of the months of December
+# or June, depending on the evolution of UT1-TAI. Bulletin C is mailed every
+# six months, either to announce a time step in UTC or to confirm that there
+# will be no time step at the next possible date.
