SETTIME - which time server still supports port-13?
« on: March 13, 2026, 03:22:20 pm »
I've been using the SETTIME utility for a long time now, but most recently noted that it no longer succeeds connecting to numerous official time servers on port-13. This is a standard DAYTIME protocol port.

In my case I've been using time.nist.gov, and sure enough looking up their published info while they state that DAYTIME protocol is still supported, they also ecourage folks to switch away and move to some of the more robust protocols.

OK, so therein lies the difficulty: what other time-set utils do we have that actually work for us?

Thanks!

Well, there is the one that ships with ArcaOS, "The Clock Synchronization Utility" somewhere on your ISO. For command line, os2_ntpd, https://hobbesarchive.com/Home/Download?path=/Hobbes/pub/os2/util/time/NTPD_1-7b.zip

 Used Nistime forever.

 readme:
NISTIME is a TCP/IP application which queries NIST time servers using the
SNTP (RFC 2030) or Daytime (RFC 867) services and adjusts the OS/2 system
clock.

Adjust servers to your need
