How about "use a command-line picker", e.g.

	$ tzid "Dusseldorf"
	$ tzid "San Francisco"
	$ tzid "San Francisco, Córdoba"
	$ tzid "San Francisco, Cordoba"
	$ tzid "Beijing"

Such a command would actually be better than some of the GUI pickers I've seen, as it actually handles cities other than the one that happened to be chosen for the tzid of the region in which it resides.  It could presumably share the databases it uses with GUI pickers in the same OS, if any.
