For example, when TZ="EET\-2EEST" and there is no TZif file "EET\-2EEST",
the idea was to adapt the transition times from a TZif file with the

POSIX does not specify the details of this obsolete transformational behavior,
the default rules are installation-dependent, and no implementation
is known to support this feature for timestamps past 2037,
so users desiring (say) Greek time should instead specify
TZ="Europe/Athens" for better historical coverage, falling back on
-TZ="EET\-2EEST,M3.5.0/3,M10.5.0/4" if POSIX conformance is required
+TZ="EET\-2EEST,M3.5.0/3,M10.5.0/4"
+if conformance to POSIX.1-2017 or earlier is required
and older timestamps need not be handled accurately.
