The other issue with leap-seconds is that python's datetime doesn't support them :-)
That's not entirely true. Since the implementation of PEP 495, it is possible to represent the 23:59:60 as 23:59:59 with the "fold" bit set. Of course, the repeated 23:59:59 will be displayed and behave exactly the same as the first 23:59:59, but a 3rd party library can be written to take the "fold" bit into account in temporal operations.
Does that support the other way -- or do we never lose a leap second anyway? (showing ignorance here) But still, now datetime *could* support leap seconds (which is nice, because before, 23:59:60 was illegal, so it couldn't even be done at all), but that doesn't mean that it DOES support leap seconds.... -CHB -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker@noaa.gov
