Erik, TJ, Dave:

TJ found that gpstime on h1guardian1 is warning of an expired leapseconds file. The file in question is /usr/share/zoneinfo/leapseconds which has an expiration time of 1687910400 in UNIX seconds which is Tue 27 Jun 2023 05:00:00 PM PDT.

Currently H1 is locked for commissioning, so we don't want to do any updates on h1guardian1 at this time. As a temporary measure I increased the expiration time to 1787910400, Fri 28 Aug 2026 02:46:40 AM PDT by manually editing the file.
