NAME

6       datezone - Convert DATE/TIMEs between timezones.
7

SYNOPSIS

9       datezone [OPTION]...  [ZONENAME]... [DATE/TIME]...
10

DESCRIPTION

12       Convert  DATE/TIMEs  between  timezones.   If  DATE/TIME is omitted, it
13       defaults to `now'.
14
15       DATE/TIME can also be one of the following specials
16         - `now'           interpreted as the current (UTC) time stamp
17         - `time'          the time part of the current (UTC) time stamp
18         - `today'         the current date (according to UTC)
19         - `tomo[rrow]'    tomorrow's date (according to UTC)
20         - `y[ester]day'   yesterday's date (according to UTC)
21
22       When DATE/TIME is a date (i.e.  the  time  component  is  omitted)  the
23       result will show the timezone offset at the end of that day.
24
25       When  DATE/TIME is a time (i.e. the date component is omitted) the con‐
26       version takes place on the date as specified by --base|-b,  by  default
27       the current date.

30       Recognized OPTIONs:
31
32       -h, --help
33              display this help and exit
34
35       -V, --version
36              output version information and exit
37
38       -q, --quiet
39              Suppress  message  about date/time or zonename parser errors and
40              fix-ups.  The default is to print a  warning  or  the  fixed  up
41              value and return error code 2.
42
43       -b, --base=DT
44              For underspecified input use DT as a fallback to fill in missing
45              fields.  Also used for ambiguous format specifiers  to  position
46              their  range  on the absolute time line.  Must be a date/time in
47              ISO8601 format.  If omitted defaults to the current date/time.
48
49       -i, --input-format=STRING...
50              Input format, can be used multiple times.  Each  date/time  will
51              be  passed  to  the  input  format parsers in the order they are
52              given, if a date/time can be  read  successfully  with  a  given
53              input format specifier string, that value will be used.
54
55       --from-locale=LOCALE
56              Interpret  dates on stdin or the command line as coming from the
57              locale LOCALE, this would only affect month and weekday names as
58              input formats have to be specified explicitly.
59
60       --from-zone=ZONE
61              Interpret  dates on stdin or the command line as coming from the
62              time zone ZONE.
63
64       --next Show next transition from/to DST.
65
66       --prev Show previous transition from/to DST.
67

FORMAT SPECS

69       Format specs in dateutils are similar to posix' strftime().
70
71       However, due to a broader range of supported calendars  dateutils  must
72       employ different rules.
73
74       Date specs:
75         %a  The abbreviated weekday name
76         %A  The full weekday name
77         %_a The weekday name shortened to a single character (MTWRFAS)
78         %b  The abbreviated month name
79         %B  The full month name
80         %_b The month name shortened to a single character (FGHJKMNQUVXZ)
81         %c  The count of the weekday within the month (range 00 to 05)
82         %C  The count of the weekday within the year (range 00 to 53)
83         %d  The day of the month, 2 digits (range 00 to 31)
84         %D  The day of the year, 3 digits (range 000 to 366)
85         %F  Equivalent to %Y-%m-%d (ymd's canonical format)
86         %g  ISO week date year without the century (range 00 to 99)
87         %G  ISO week date year including the century
88         %j  Equivalent to %D

146
147       For  conformity here is a list of calendar designators and their corre‐
148       sponding format string:
149         ymd     %Y-%m-%d
150         ymcw    %Y-%m-%c-%w
151         ywd     %rY-W%V-%u
152         bizda   %Y-%m-%db
153         lilian     n/a
154         ldn        n/a
155         julian     n/a
156         jdn        n/a
157         matlab     n/a
158         mdn        n/a
159
160       These designators can  be  used  as  output  format  string,  moreover,
161       @code{lilian}/@code{ldn}  and @code{julian}/@code{jdn} can also be used
162       as input format string.
