# TZ="" ; export TZ

# The TZ variable overrides the default timezone. The value of the TZ variable can be either a POSIX timezone specification [1]
# or the name of a zoneinfo binary format timezone file [2] (the form used by glibc and most all other systems).
# See also, the "References" section below.

# POSIX timezone conventions

# std offset [dst[offset][,start[/time],end[/time]]]
#
# std, dst: arbitrary mnemonics. 'std (dst) + offset = UTC'
# offset: (+-)hh[:mm[:ss]] (note: the offset for 'std' must be specified!! The sign is mandatory!!)
# time: hh[:mm[:ss]]
#
#
# start: date of the schedule changes from 'std' to 'dst'
# end: date of the schedule changes from 'dst' to 'std'
#
# - date: either Jn, n or Mm,n,d
# -- Jn "Julian day": (1 <= n <= 365) (60: 01 march)
# -- n "Julian zero-based day": (0 <= n <= 365) [60: 29 february)
# -- Mm.n.d: (m: month, n: week, d: day)  || n: [1 = "first week", 5 = "fifth week"] || d: [0 -> "sunday", 6 -> "saturday"]
# --- (1 <= m <= 12) ; (1 <= n <= 5) ; (0 <= d <= 6)

# Examples:
#
# a) TZ="CST+6CDT"
# b) TZ="NFT-1DST-02:00,M3.5.0,M10.5.0" 
# c) TZ="NZST-12:00:00NZDT-13:00:00,M10.1.0,M3.3.0"
# d) TZ="DMA+3"
#
# a) 'std' is six hours behind UTC, 'dst' is seven hours behind UTC (deduced implicitly because not specified)
# b) 'std' is one hour ahead UTC, 'dst' is two hours ahead UTC (note: the minutes are specified)
# c) 'std' is twelve hours ahead UTC, 'dst'..., schedule changes the 'first time' the sunday of the first week of october.
# d) 'std' is three hours behind UTC (note: offset is the value added to the local time to arrive at Coordinated Universal Time).
