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 well-known name "posixrules" that is present only - for this purpose and is a copy of the file "Europe/Brussels", a file + a TZif file with the well-known name "posixrules" that was present only + for this purpose and was a copy of the file "Europe/Brussels", a file with a different UT offset. 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 - and older timestamps need not be handled accurately. + on 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. The localtime(3) function normally uses the first ttinfo structure in the file if either tzh_timecnt is zero or the time argument is less |
