Have there actually been any time zones that are not an even multiple of a whole minute since the advent of leap seconds?

Yes, some locations not in the tz database still use times that are not a multiple of a whole minute. One example is the Vatopedi monastery on Mt Athos. You can see Wim Voogd's 2013 photo of the Vatopedi clock, which still keeps Byzantine time, here: https://athosweblog.files.wordpress.com/2014/04/dscn2077-large.jpg Not much has changed since Harry Griswold Dwight's circa-1915 photograph: http://www.natgeocreative.com/comp/IR18/199/603213.jpg The tz code and data as currently constituted cannot feasibly represent Byzantine time.
