- GMT and UTC are not the same.
-
- The following is a list of leap seconds which have been added to
- Universal Coordinated Time (UTC) in order to keep it relatively close to
- solar time. Note that with Greewich Mean Time, such corrections were
- made by stretching or contracting the length of seconds. UTC is
- generally available through time standards, GMT not readily available.

- This is data derived from an AP story from May 1985. No data since then
- is known. There is also no indication whether the insertions were made
- in local time or in UTC. Local time is assumed. (Wouldn't Australia,
- Newfoundland, and other half-hour-off places have fun with inserting an
- extra second in the middle of a pseudo-random hour.)
-
- This information has been pieced together from scattered sources. I
- reserve the right to be proven wrong.
