I ended up going with the string-based timezone as I was worried that
the sign of the timezone could easily confuse people because the SQL
timezone offset sign is often different from the OS timezone.  The new
output is:

        ;
        ; Archive created at Wed Sep  3 16:12:21 2014 EST   <--
        ;     dbname: test
        ;     TOC Entries: 8
        ;     Compression: -1
        ;     Dump Version: 1.12-0
        ;     Format: CUSTOM
        ;     Integer: 4 bytes
        ;     Offset: 8 bytes
        ;     Dumped from database version: 9.5devel
        ;     Dumped by pg_dump version: 9.5devel

Patch attached.
