Since 2020-01-01 the ITA server Webmin interface Setup and Status pages may display:
Error: It seems the server was installed in the future. Please verify the server time is correct and reinstall the server.
This is the so-called 2020 effect, buried deep in the Unix/Linux system (Perl related). Starting from January 1, 2020, when making any date comparison operation with the year 1970 (the origin of Unix time), the date becomes 2070.
Although this does not seem to affect the ITA server functionality at all, this is expected to be fixed as soon as possible.
Update: fixed in latest release version(s).
