# Allowance for leap seconds added to each time zone file. 
 
# This file is in the public domain. 
 
# This file is generated automatically from the data in the public-domain 
# leap-seconds.list file, which is copied from:

# For more about leap-seconds.list, please see 
# The NTP Timescale and Leap Seconds 
# https://www.eecis.udel.edu/~mills/leap.html 
 
# 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 
# Levine J. Coordinated Universal Time and the leap second.

# 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
