40*bc421551SDag-Erling Smørgrav# Such a setting uses the rules in a template file to determine
41*bc421551SDag-Erling Smørgrav# "spring forward" and "fall back" days and times; the environment

46*bc421551SDag-Erling Smørgrav# Any other value for POSIXRULES is obsolete and should not be relied on, as:
47*bc421551SDag-Erling Smørgrav# * It does not work correctly in popular implementations such as GNU/Linux.
48*bc421551SDag-Erling Smørgrav# * It does not work even in tzcode, except for historical timestamps

50*bc421551SDag-Erling Smørgrav#   Hence it typically does not work for current and future timestamps.
51*bc421551SDag-Erling Smørgrav# In short, software should avoid ruleless settings like TZ='EET-2EEST'
