From a8d938c4ed93aa03fc87c9173aaee4e26ee67c5b Mon Sep 17 00:00:00 2001 From: Dale Mellor Date: Mon, 20 Apr 2020 11:27:53 +0000 Subject: test: make date tests reliable, i.e. independent of current time Some of the date tests depend both on the particular time of day and year at which the test is run, and also on the state of daylight-savings adjustments. (At the present time on my system there are four failing tests, but YMMV.)
