Issue #3299 has been updated by daftaupe.
I could reproduce on a KVM vm of mine after a random reboot
<pre><code class="shell">

I will try to keep it on for some time see if that resolves by itself after some time, but time is already synchronized and accurate

----------------------------------------
Bug #3299: DragonFlyBSD reports utterly wrong uptime (most of the time, right after booting in)
http://bugs.dragonflybsd.org/issues/3299#change-14455
* Author: adrian
* Status: In Progress
* Priority: Normal
* Category: Userland
* Target version: 6.4
* Start date: 2021-10-25
----------------------------------------
System environment:
<pre>
root at dragonflybsd /home/adrian
# uname -a
DragonFly dragonflybsd.v-zone.lan.dac 6.0-RELEASE DragonFly v6.0.1-RELEASE #1: Thu Oct 14 18:25:27 CEST 2021 adrian at dragonflybsd.v-zone.lan.dac:/usr/obj/usr/src/sys/X86_64_GENERIC x86_64
</pre>
Running DragonFlyBSD inside a Debian KVM(qemu) virtualization as a guest with hardware acceleration,
the system reports a very wrong uptime, issuing "uptime".
Gkrellm even reports a negative, very strange uptime! Check by running gkrellm from the pkg system.
After ~2 days of uptime, I see this wrong uptime:
<pre>
root at dragonflybsd /home/adrian
# uptime
6:35PM up 42954 days, 10:01, 2 users, load averages: 0,00 0,00 0,00
</pre>
The error also was present with Version 6.0.0. This is now Version 6.0.1 and the bug is still there.
Happens about three of four times, the bug is present right after booting into the system.
Thank you for taking the time reading this.
Sincerely,
Adrian Kieß
