commit e385fc421f331989f2e6518465e5ead42e5a0618
from: Stefan Sperling <stsp@stsp.name>
date: Mon Aug 30 15:48:05 2021 UTC

use gmtime_r(3) instead of localtime_r(3) to display time in UTC as intended

Problem noticed by naddy due to failing regress tests at midnight, and then
analyzed with additional help from millert.

ok naddy
