time/xchrono 19900813nb2 NetBSD

Xchrono is a multi-timezone, multi-face clock program for X Windows. Several cities have been compiled into xchrono, and can be invoked with command-line arguments, xchrono -help gives:

Usage: xchrono [-analog] [-bw <pixels>] [-digital] [-fg <color>] [-bg <color>] [-hd <color>] [-hl <color>] [-bd <color>] [-fn <font_name>] [-help] [-padding <pixels>] [-rv] [-update <seconds>] [-display displayname] [-geometry geom] [-width clockWidth] [-height clockHeight] [-local localName] [-boston] [-newyork] [-chicago] [-denver] [-la] [-hawaii] [-tokyo] [-sydney] [-london] [-paris] [-frankfurt] [-rio]

OK, OK, Hawaii isn't a city, but you get the point. The timezones used are taken from tztab in the SYSV case, and from /usr/lib/zoneinfo otherwise, and as such may or may not be correct (the TZ variable definitions or the city->timezone mappings).

The -local <localName> option causes a clock labeled with <localName> using the value of TZ at startup as its timezone. In addition, a GMT clock always appears.
