Description Ionut Nechita 2021-01-28 17:38:31 UTC

Hi SUSE Team,

I try to set date with UTC format and 2038 Year.
This is not working.

Steps for reproduce:
# date -s "Jan 20 15:42:59 UTC 2038"
# hwclock -w
# hwclock -s


hwclock: settimeofday() failed: Invalid argument

Comment 1 Stanislav Brabec 2022-05-20 01:32:40 UTC

Can you reproduce it with util-linux-2.37.4 in the recent Tumbleweed? I cannot reproduce it there.

This is still an expected behavior for 32-bit platforms, but it should not happen on 64 bits.

Hi Stanislav,

I try today with latest util-linux and this issue is not reproduced on my system.
Thank you for all.

Bisect indicates this as the fix:
https://github.com/util-linux/util-linux/commit/a937ef831891c30bb7adfc945dee439d192b3476

But there is at least one another relevant commit we might need to backport:
https://github.com/util-linux/util-linux/commit/ce3355cc54d97711bc240783324f7ab51fd6e371

Comment 5 Marcus Meissner 2022-06-14 07:02:04 UTC

we have so far not committed to any product after this year.

ALP however would need to be covered.

Thorsten, you did some work on this y2038 problem, is this correct?

Comment 6 Stanislav Brabec 2022-06-15 22:11:46 UTC

git describe --contains a937ef831891c30bb7adfc945dee439d192b3476
v2.37-rc2~37^2~2

=> Anything newer than SLE15 SP4 is not affected by this Y2038 bug.
