Hi Yasu,

Yes.  Please don't send HTML e-mail to mailing lists: most people 
don't like receiving it (e.g., sending me HTML mail is guaranteed 
to land you in my Spam bin) & you never know how your mail will 
appear to others.

Yes.  We have enabled both ‘convert text/html parts to plain text’ 
and ‘collapse multipart/alternative to its first part content’.

I get the same error, with the tzdata Racket (and Guix, just in 
case) package install.

If I manually add $(guix build tzdata)/share/zoneinfo to
pkgs/tzinfo/tzinfo/private/zoneinfo.rkt's 
default-zoneinfo-search-path, it works.

However, I didn't notice a $TZDIR-like mechanism to do so 
‘properly’.

Kind regards,
