Erratic behavior in Erlang/erts after ~14 years of stability. Adjust system time and all is fine again.

We have been running Erlang R14B (erts-5.8.1) since 2010 and things have been fine. Starting last Friday (13th as it was) at just past 8:19am CST, we started seeing issues with what is being reported back from network nodes to the main interface window. Details of machine names, number of traces being passed etc are not being reported anymore. IF I reset the linux time back before 8:15 Friday morning, then it all works as it has for 14 years. Move it forward again past 8:15, then it stops reporting etc.

I know we have a very old version and need to move to a newer version, but that won’t happen in the short term. It is in the long term plans. Does anyone know of a time issue related to Friday the 13, 2024 around 8am CST?

Linux Centos 6.7
Erlang R14B
Erts 5.8.1
