[New-bugs-announce] [issue18718] datetime documentation contradictory on leap second support

[David Wolever]

New submission from David Wolever:

The documentation for the `%S` formatter suggests that it supports leap seconds, but the footnote contradicts that:

> The range really is 0 to 61; according to the Posix standard this
> accounts for leap seconds and the (very rare) double leap seconds.
> The time module may produce and does accept leap seconds since it is
> based on the Posix standard, but the datetime module does not accept
> leap seconds in strptime() input nor will it produce them in
> strftime() output.

I propose that the documentation be updated to mirror the 3.X documentation: no leap second in the example and a footnote which makes note of that and suggests using the time module.
