Here's a working patch to make formatting of a DateTime instance work as generally expected, when you use <dtml-var "_.DateTime()" fmt="%d %G %z"> or whatever. It could be made more efficient by compiling the two regex (regexes? regexen? regular expressions :-) ) into class attributes. Here's the method I changed: def strftime(self, format): diff=_tzoffset(self._tz, self._t) format = ts_regex.gsub('\(^\|[^%]\)%Z', '\\1'+self._tz, format) format = ts_regex.gsub('\(^\|[^%]\)%z', '\\1%+05d' % (diff/36), format) return strftime(format, gmtime(self.timeTime()+diff)) Instead of just calling gmtime with the time as held in the DateTime instace, it subverts time.strftime into formatting the time shifted according to the instance's timezone. Because time.strftime won't format the timezone information correctly, this is done using regular expressions before the format specification string is passed to time.strftime. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net *** lib/python/DateTime/DateTime.old.py Sun Jul 23 20:03:04 2000 --- lib/python/DateTime/DateTime.py Mon Jul 24 14:01:37 2000 *************** *** 1376,1382 **** return millis def strftime(self, format): ! return strftime(format, gmtime(self.timeTime())) # General formats from previous DateTime def Date(self): --- 1376,1385 ---- return millis def strftime(self, format): ! diff=_tzoffset(self._tz, self._t) ! format = ts_regex.gsub('\(^\|[^%]\)%Z', '\\1'+self._tz, format) ! format = ts_regex.gsub('\(^\|[^%]\)%z', '\\1%+05d' % (diff/36), format) ! return strftime(format, gmtime(self.timeTime()+diff)) # General formats from previous DateTime def Date(self):
