Reported by: Roman Bogorodskiy <bogorodskiy@gmail.com> Some of the tests for virTimeLocalOffsetFromUTC set an imaginary timezone that attempts to force dyalight savings time active all the time by setting a start date of 0/00:00:00 and end date of 366/23:59:59. Since the day is 0-based, 366 really means "day 367" which will never occur - this was an attempt to eliminate problems with DST not being active in some cases right around midnight on January 1. Even though it didn't completely solve the problem, it didn't seem to cause harm so it was left in the test timezones. Although Linux glibc doesn't mind having a DST end date of 366, FreeBSD refuses to use such timezones, so the tests fail. This patch changes the 366 to 365. This may or may not cause failure of the remaining DST tests around midnight Jan 1. If so, we will need to disable those tests at year's end too.
