These _might_ help you understand this confusing subject. For me |
| 14 |
they just gave me a headache. The best I can tell POSIX handling |
| 15 |
of time-keeping is just broken. In short, don't worry too much |
| 16 |
about it. If you really want to know what time it is use GPS time |
| 17 |
(a sane TAI-based system), then convert that to UTC. |
