Good Morning,

A few days ago chrony 4.9 was released with support for OpenBSD 
including pledge(2) support and support for refclock driver for OpenBSD 
timedelta sensors.

I'd very much welcome feedback and testing of chrony.

For anyone not knowing what chrony is used for, here a short introduction:

chrony is a versatile implementation of the Network Time Protocol (NTP). 
It can synchronise the system clock with NTP servers, reference clocks 
(e.g. GPS receiver), and manual input using wristwatch and keyboard. It 
can also operate as an NTPv4 (RFC 5905) server and peer to provide a 
time service to other computers in the network.

The news about 4.9 (and previous versions) can be found at :
	https://chrony-project.org/news.html

Find attached the OpenBSD ports archive for it.

It run under the user _chrony which would have to be added to the 
user.list beforehand with user ID 906, the lowest unused ID as of 
today/2026-08-30.

The archive's content corresponds to tag 4.9 on my git repo
https://git.sr.ht/~patient0/chrony-OpenBSD-ports

A note regarding dependencies:

- it links against gnutls and nettle. On -current gnutls links against
   nettle 4 (security/nettle) and that is how this port is setup at the
   moment.
   On OpenBSD < 8.0 gnutls links against nettle 3, named
   security/libnettle. If one wants to compile chrony for OpenBSD < 8.0
   you would have to change the Makefile accordingly.
   Does it make sense to adapt the Makefile to handle this situation or
   is handling -current only recommended?


Have an excellent Sunday
