ID: 45483 Comment by: tj at systisoft dot com Reported By: tj at systisoft dot com Status: Assigned Bug Type: Feature/Change Request Operating System: All PHP Version: 5.3CVS-2008-07-11 (CVS) Assigned To: derick New Comment:
On further thinking there should be a new format char for BC dates because Y formats the date with year 0 which is conforming with ISO8601. But years in the proleptic Gregorian calendar do not have a year 0. The year 0 in ISO8601 is 1 BC in the proleptic Gregorian calendar. Previous Comments: ------------------------------------------------------------------------ [2008-07-15 11:47:34] tj at systisoft dot com There should also be a possibility to format a year without the sign, because if you format with 'Y' you will get something like: -2000 BC This can either be done by an new format char for unsigned year or that the 'Y' format is omitting the sign when a format char for the era designator is present. ------------------------------------------------------------------------ [2008-07-11 10:18:11] tj at systisoft dot com Description: ------------ It is currently not possible to specify an era designator in a format when parsing or formatting dates with DateTime::createFromFormat or DateTime::format. An era designater would be BC or AD as in 1/1/0200 BC or 1/1/2004 AD. I don't know which format char would be good since 'G' which is used in some other format patterns as era designator seems to be already taken.
