Yes, it is, but what string would you translate +0200 to?  There are
numerous time-zone names that map to the same offset at any given
time.  It is impossible to use just one random time-zone name for this
translation, because tomorrow some of them will switch to +0300, while
others will not.

In other words, if the offset is all you care about, you could simply
use %z, and be done with it.  This isn't the problem we are
discussing.
