No. There cannot be, see below.

Unfortunately, the mapping is neither 1-1 nor language independent.
For example, EST means UTC-0500 in the U.S., but UTC+1100 in Australia.
Furthermore, the 3-letter zones used in TZ software are English-based,
and often have nothing to do with the zone names used in
non-English-speaking countries. Furthermore, many countries probably
don't have official abbreviations, especially when they have only
one time zone (the norm).
All that is why TZ uses the continent/country form to specify zones.
