1.16 millert 3: # DATAFORM selects the data format. OpenBSD always uses "main"
4: # Available formats represent essentially the same data, albeit
5: # possibly with minor discrepancies that users are not likely to notice.
6: # To get new features and the best data right away, use:
7: # DATAFORM= vanguard
8: # To wait a while before using new features, to give downstream users
9: # time to upgrade zic (the default), use:
10: # DATAFORM= main
11: # To wait even longer for new features, use:
12: # DATAFORM= rearguard
13: # Rearguard users might also want "ZFLAGS = -b fat"; see below.
14: DATAFORM= main
15:
16: # The POSIXRULES macro controls interpretation of POSIX-like TZ
17: # settings like TZ='EET-2EEST' that lack DST transition rules.
18: # If POSIXRULES is '-', no template is installed; this is the default.
19: # Any other value for POSIXRULES is obsolete and should not be relied on, as:
20: # * It does not work correctly in popular implementations such as GNU/Linux.
21: # * It does not work even in tzcode, except for historical timestamps
22: # that precede the last explicit transition in the POSIXRULES file.
23: # Hence it typically does not work for current and future timestamps.
24: # If, despite the above, you want a template for handling these settings,
25: # you can change the line below (after finding the timezone you want in the
26: # one of the $(TDATA) source files, or adding it to a source file).
27: # Alternatively, if you discover you've got the wrong timezone, you can just
28: # 'zic -p -' to remove it, or 'zic -p rightzone' to change it.
29: # Use the command
30: # make zonenames
31: # to get a list of the values you can use for POSIXRULES.

1.16 millert 40: # What kind of TZif data files to generate. (TZif is the binary time
41: # zone data format that zic generates; see Internet RFC 8536.)
42: # If you want only POSIX time, with time values interpreted as
43: # seconds since the epoch (not counting leap seconds), use
44: # REDO= posix_only
45: # below. If you want only "right" time, with values interpreted
46: # as seconds since the epoch (counting leap seconds), use
1.1 deraadt 47: # REDO= right_only
48: # below. If you want both sets of data available, with leap seconds not
49: # counted normally, use

51: # below. If you want both sets of data available, with leap seconds counted
52: # normally, use
53: # REDO= right_posix
1.16 millert 54: # below. POSIX mandates that leap seconds not be counted; for compatibility
55: # with it, use "posix_only" or "posix_right". Use POSIX time on systems with
56: # leap smearing; this can work better than unsmeared "right" time with
57: # applications that are not leap second aware, and is closer to unsmeared
58: # "right" time than unsmeared POSIX time is (e.g., 0.5 vs 1.0 s max error).
59: REDO= posix_only

1.16 millert 61: # Whether to put an "Expires" line in the leapseconds file.
62: # Use EXPIRES_LINE=1 to put the line in, 0 to omit it.
63: # The EXPIRES_LINE value matters only if REDO's value contains "right".
64: # If you change EXPIRES_LINE, remove the leapseconds file before running "make".
65: # zic's support for the Expires line was introduced in tzdb 2020a,
66: # and was modified in tzdb 2021b to generate version 4 TZif files.
67: # EXPIRES_LINE defaults to 0 for now so that the leapseconds file
68: # can be given to pre-2020a zic implementations and so that TZif files
69: # built by newer zic implementations can be read by pre-2021b libraries.
70: EXPIRES_LINE= 0

72: # To install data in text form that has all the information of the TZif data,
73: # (optionally incorporating leap second information), use
74: # TZDATA_TEXT= tzdata.zi leapseconds
75: # To install text data without leap second information (e.g., because
76: # REDO='posix_only'), use

78: # To avoid installing text data, use
