# The POSIXRULES macro controls interpretation of nonstandard and obsolete
|
|
# POSIX-like TZ settings like TZ='EET-2EEST' that lack DST transition rules.
|
|
# Such a setting uses the rules in a template file to determine
|
|
# "spring forward" and "fall back" days and times; the environment
|
|
# variable itself specifies UT offsets of standard and daylight saving time.
|
|
#
|
|
# If POSIXRULES is '-', no template is installed; this is the default.
|
|
#
|
|
# Any other value for POSIXRULES is obsolete and should not be relied on, as:
|
|
# * It does not work correctly in popular implementations such as GNU/Linux.
|
|
# * It does not work even in tzcode, except for historical timestamps
|
|
# that precede the last explicit transition in the POSIXRULES file.
|
|
# Hence it typically does not work for current and future timestamps.
|
|
# In short, software should avoid ruleless settings like TZ='EET-2EEST'
|
|
# and so should not depend on the value of POSIXRULES.
|
|
#
|
|
# If, despite the above, you want a template for handling these settings,
|
|
# you can change the line below (after finding the timezone you want in the
|
|
# one of the $(TDATA) source files, or adding it to a source file).
