Subject: [PATCH] timers: Lower base clock forwarding threshold
Git-commit: 36cd28a4cdd05d47ccb62a2d86e8f37839cc879a
Patch-mainline: v5.9-rc1
References: bsc#1179365
There is nothing that prevents from forwarding the base clock if it's one
jiffy off. The reason for this arbitrary limit of two jiffies is historical
and does not longer exist.
