Hi Andrew, I ran git bisect which found the following as the first faulty commit:
6c691b3e5099de380a9d2f97d5c72f4a978bb794 is the first bad commit

jobs: Only clear gotsigchld when waiting for everything
The gotsigchld flag is always cleared in dowait but not all callers
of dowait will wait for everything. In particular, when jp is set
we only wait until the set job isn't running anymore.
This patch fixes this by only clearing gotsigchld if jp is unset.
It also changes the waitcmd to actually set jp which corresponds
to the behaviour of bash/ksh93/mksh.
The only other caller of dowait that doesn't wait for everything
is the jobless reaper. This is in fact redundant now that we wait
after every simple command. This patch removes it.
Finally as every caller of dowait needs to wait until either the
given job is not running, or until all terminated jobs have been
processed, this patch moves the loop into dowait itself.
Fixes: 03876c0743a5 ("eval: Reap zombies after built-in...")

As you asked on IRC, to reproduce the problem I used autopkgtest with
LXC like this (on sid)
# autopkgtest-build-lxc debian sid
# autopkgtest --test-name=timedated systemd -- lxc -s autopkgtest-sid
If you want to edit the timedated script, you can also use
# apt-get source systemd
# vi systemd-246.6/debian/tests/timedated
# autopkgtest --test-name=timedated systemd-246.6/ -B -- lxc -s
autopkgtest-sid
