This is the second time I've encountered this issue in roughly a week.. this time it happend while I was actively using the VM (evidently, not a sleep/suspend issue).. The system clock on my guest host spontaneously jumped forward from February 18 2024 (current time) to a remarkable April 11 2119 The last time this occured it was resolved with a reboot of the guest OS, though I had to resolve a bunch of timestamps that caused dependency issues in my build system (because obviously a file dated 95 years in the future is newer than the binary I'm trying to build in 2024) I can't say this is specifically a Parallels issue, though I don't encounter such problems on physical hardware timedatectl shows the following $ timedatectl Local time: Tue 2119-04-11 02:10:36 AEST Universal time: Mon 2119-04-10 16:10:36 UTC RTC time: Sat 2024-02-17 14:21:40 Time zone: Australia/Sydney (AEST, +1000) System clock synchronized: no NTP service: active RTC in local TZ: no The guest VM is configured to sync with my mac, and the time shows on the host OS as normal. I've tried restarting chrony, but ultimately the only fix I can see is to reboot the guest OS After doing so, timedatectl shows correctly $ timedatectl Local time: Sun 2024-02-18 01:29:03 AEDT Universal time: Sat 2024-02-17 14:29:03 UTC RTC time: Sat 2024-02-17 14:29:04 Time zone: Australia/Sydney (AEDT, +1100) System clock synchronized: yes NTP service: active RTC in local TZ: no chronyd journal logs at the time indicate the following: Feb 17 11:40:30 fedora-39-arm64-kde chronyd[947]: Forward time jump detected!
