# The International Earth Rotation and Reference Systems 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,

|
# 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
