Subject: Issue #11188, #19748: mktime() returns -1 on error. On Linux, the tm_wday field
X-Git-Tag: v3.4.1rc1~233^2~247
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8c8b4e0ebf5f58fae2d10453cda9d4ee614794d9;p=python

Issue #11188, #19748: mktime() returns -1 on error. On Linux, the tm_wday field
is used as a sentinel () to detect if -1 is really an error or a valid
timestamp. On AIX, tm_wday is unchanged even on success and so cannot be used
as a sentinel.
