One open question regarding leap seconds has been what to do with power grids so that clocks with motors that run synchronously with the AC power will experience 86400 * (50 or 60) cycles in a UTC day even if there is a leap second. Some reports have indicated that many grids adjust their frequencies on the day of a leap second such that such clocks will retain sub-second accuracy.
In light of recent world events on power grids, I'll offer that this might no longer be considered as a relevant issue. The grids should just keep atomic frequency. Clock owners appear likely to need to reset them much more often than every leap second. -- Steve Allen UCO/Lick Observatory Santa Cruz, CA 95064 [EMAIL PROTECTED] Voice: +1 831 459 3046 http://www.ucolick.org/~sla PGP: 1024/E46978C5 F6 78 D1 10 62 94 8F 2E 49 89 0E FE 26 B4 14 93
