6.8.1.1 Diary Messages
......................
‘nndiary’ messages are just normal ones, except for the mandatory
presence of 7 special headers. These headers are of the form
‘X-Diary-<something>’, ‘<something>’ being one of ‘Minute’, ‘Hour’,
‘Dom’, ‘Month’, ‘Year’, ‘Time-Zone’ and ‘Dow’. ‘Dom’ means “Day of
Month”, and ‘dow’ means “Day of Week”. These headers actually behave
like crontab specifications and define the event date(s):
• For all headers except the ‘Time-Zone’ one, a header value is
either a star (meaning all possible values), or a list of fields
(separated by a comma).
• A field is either an integer, or a range.
• A range is two integers separated by a dash.
• Possible integer values are 0–59 for ‘Minute’, 0–23 for ‘Hour’,
1–31 for ‘Dom’, 1–12 for ‘Month’, above 1971 for ‘Year’ and 0–6 for
‘Dow’ (0 meaning Sunday).
• As a special case, a star in either ‘Dom’ or ‘Dow’ doesn’t mean
“all possible values”, but “use only the other field”. Note that
if both are star’ed, the use of either one gives the same result.
• The ‘Time-Zone’ header is special in that it can only have one
value (‘GMT’, for instance). A star doesn’t mean “all possible
values” (because it makes no sense), but “the current local time
zone”. Most of the time, you’ll be using a star here. However,
for a list of available time zone values, see the variable
‘nndiary-headers’.
As a concrete example, here are the diary headers to add to your
message for specifying “Each Monday and each 1st of month, at 12:00,
20:00, 21:00, 22:00, 23:00 and 24:00, from 1999 to 2010” (I’ll let you
find what to do then):
X-Diary-Minute: 0
X-Diary-Hour: 12, 20-24
X-Diary-Dom: 1
X-Diary-Month: *
X-Diary-Year: 1999-2010
X-Diary-Dow: 1
X-Diary-Time-Zone: *
