# 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.

|
