Description valere.monseur 2020-04-05 09:43:21 UTC 
Hi,

I've recenctly upgraded my linux distribution (archlinux) that provides now gcc 9.3.0 and glibc 2.31.

Since the rebuild of busybox, hwclock returns an error like this:

# busybox hwclock --systz -u
hwclock: settimeofday: Invalid argument

It might be linked to glibc 2.31. I've found a related hwclock bug report in util-linux: https://github.com/karelzak/util-linux/commit/cd781c405be82540484da3bfe3d3f17a39b8eb5c

Could you please have a look and let me know what other information I need to provide?

Thanks
Regards,
V.

This has been fixed by the following commit:

commit 1a5d6fcbb5e606ab4acdf22afa26361a25f1d43b

    hwclock: Fix settimeofday for glibc v2.31+
    
    The glibc implementation changed for settimeofday, resulting in "invalid
    argument" error when attempting to set both timezone and time with a single
    call. Fix this by calling settimeofday twice
