and the bug was...not subtle, either. it just silently ignored the documented behavior of `date -r` (printing the modtime of a file) [1, 2]
as a time synchronization nerd, I've been following ntpd-rs's development, and tested it out as a possible replacement for Chrony. my overall impression is that like rust-coreutils, it's a well-intentioned project but not ready for prime-time, certainly not at the level of "installed by default on Ubuntu" (even in a non-LTS release)
for example, there's an issue that's been open for ~9 months about logging being unnecessarily verbose, and flooding the system journal [3].
and an issue titled "implement new algorithm" opened by one of the core contributors, with zero description or details [4].
these are not the hallmarks of a stable, mature open-source project.

chrony has some dependencies too but for important optional features like seccomp or capability dropping that I don't think ntpd-rs even implements...
Can they not rewrite all the other daemons in Rust as well? I would rather keep using Chrony on all the Linux distributions that I use.
