- # The International Earth Rotation and Reference Systems Service

- # (which measures the true angular orientation of the earth in space); see

- # 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.
