for this code and simplicity assumes date in nabble are as per the haxe mailing list atom:

5. DATE AND TIME SPECIFICATION
|
||||
|
||||
|
||||
|
||||
5.1. SYNTAX
|
||||
|
||||
|
||||
date-time = [ day "," ] date time ; dd mm yy
|
||||
; hh:mm:ss zzz
|
||||
|
||||
day = "Mon" / "Tue" / "Wed" / "Thu"
|
||||
/ "Fri" / "Sat" / "Sun"
|
||||
|
||||
date = 1*2DIGIT month 2DIGIT ; day month year
|
||||
; e.g. 20 Jun 82
|
||||
|
||||
month = "Jan" / "Feb" / "Mar" / "Apr"
|
||||
/ "May" / "Jun" / "Jul" / "Aug"
|
||||
/ "Sep" / "Oct" / "Nov" / "Dec"
|
||||
|
||||
time = hour zone ; ANSI and Military
|
||||
|
||||
hour = 2DIGIT ":" 2DIGIT [":" 2DIGIT]
|
||||
; 00:00:00 - 23:59:59
|
||||
|
||||
zone = "UT" / "GMT" ; Universal Time
|
||||
; North American : UT
|
||||
/ "EST" / "EDT" ; Eastern: - 5/ - 4
|
||||
/ "CST" / "CDT" ; Central: - 6/ - 5
|
||||
/ "MST" / "MDT" ; Mountain: - 7/ - 6
|
||||
/ "PST" / "PDT" ; Pacific: - 8/ - 7
|
||||
/ 1ALPHA ; Military: Z = UT;
|
||||
; A:-1; (J not used)
|
||||
; M:-12; N:+1; Y:+12
|
||||
/ ( ("+" / "-") 4DIGIT ) ; Local differential
|
||||
; hours+min. (HHMM)
|
||||
|
||||
|
||||
5.2. SEMANTICS
|
||||
|
||||
|
||||
If included, day-of-week must be the day implied by the date
|
||||
specification.
|
||||
|
||||
Time zone may be indicated in several ways. "UT" is Univer-
|
||||
sal Time (formerly called "Greenwich Mean Time"); "GMT" is per-
|
||||
mitted as a reference to Universal Time. The military standard
|
||||
uses a single character for each zone. "Z" is Universal Time.
|
||||
"A" indicates one hour earlier, and "M" indicates 12 hours ear-
|
||||
lier; "N" is one hour later, and "Y" is 12 hours later. The
|
||||
letter "J" is not used. The other remaining two forms are taken
|
||||
from ANSI standard X3.51-1975. One allows explicit indication of
|
||||
the amount of offset from UT; the other uses common 3-character
|
||||
strings for indicating time zones in North America.
