I do too, now.  :-)

a better suggestion would have been:

  [locale]
  tz = {local|utc}
  lang = en_GB.utf8

as you say, conf provides environment type info.  given that 'strftime()' uses
locale, a setting to provide a preference/default could be useful.  (POV-Ray
appears to use the locale already, anyway)

ok, did not know that.

sure, thought setting a convenient default, and override in 'datetime()'s second
arg, if required.
