I have repeatedly made the assertion that the finer points of
timekeeping escapes the average engineer or programmer and that
leap-seconds are a fine point to be avoided for that reason.

NASA has released a brand new report about Crew survival in Columbias
disintegration: http://www.nasa.gov/news/reports/index.html

Page XVII, the glossary has an entry

GMT Greenwich Mean Time

But it has no entry for UTC, UT1 any other UT (or leap seconds).

Throughout the report, GMT is used for time reference.

For instance: page 2-12 has the following figure label:

Figure 2.1-13. Entry simulation snapshot sequence. Times
are in Greenwich Mean Time.

Never attribute to malice what can adequately be explained by incompetence.
