Simon Arlott a écrit :
RFC 1305 doesn't say that it must not be set more than 24 hours early, it just states that it must
be set more at least 1 minute before it happens:

Leap Indicator (sys.leap, peer.leap, pkt.leap): This is a two-bit code
warning of an impending leap second to be inserted in the NTP timescale.
The bits are set before 23:59 on the day of insertion and reset after
00:00 on the following day. This causes the number of seconds (rollover
interval) in the day of insertion to be increased or decreased by one.
(Later in the RFC it does say it would be set on the day before.)
Perhaps I'm missing something here, but this means that the Leap Indicator is set on and only on the day of insertion. The Leap Indicator is about telling other servers that there will be a leap second on a given day (so that they don't have to slowly drift to get back in sync), it only has a meaning the day of the insertion.

So, it's very clear to me that *no* leap indicator should be set by now. Are 27,7% of the servers wrong? (or simply assuming that leap seconds only occurs at the end of December or June?)
