The number of seconds since the epoch doesn't change, but the
presentation does.

No, this is setting the TZ environment variable for the duration of the
date command.

eg:

[dick at hagbard ~] [ 9:20] 
:; TZ=GMT date
Fri Nov 28 09:20:55 GMT 2003

[dick at hagbard ~] [ 9:20] 
:; TZ=Cuba date
Fri Nov 28 04:21:19 CST 2003

[dick at hagbard ~] [ 9:21] 
:; TZ=Pacific/Galapagos date
Fri Nov 28 03:22:24 GALT 2003
