Re: [TCLCORE] Reminder on TCL call next Monday 11th of November 2024 at 12:00 UTC

It is not THE CLOCK PATTERN "%Z", but the TZ-NAME in many
timezone-definitions in library/tzdata got "%z" in 8.6.15, 
instead of for instance "±0100"...
As mentioned in the ticket, the regression was [9275edd424971958] [2]
and how one can see, that affects many tzdata files.
To be more clear, all scan- and format-attempts could be affected, where
current TZ (and the timestamp) would 
match or result to such zone blocks, for instance: 

% clock format [clock seconds] -timezone :Pacific/Norfolk;
Sat Nov 09 06:17:17 %Z 2024
% clock format [clock seconds] -timezone :Etc/GMT-1;
Fri Nov 08 20:17:18 %Z 2024
