| # 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. |
