I try use datetime and timedelta in an External Method and returns an error to ....

Error Type: ImportError Error Value: No module named datetime

There's any way to import this module in Zope or I must create a new product for it.

Use the DateTime module in Zope. If you need datetime and timedelta, you can convert between DateTime and datetime with (untested): from DateTime import DateTime from datetime import tzinfo ZERO = timedelta(0) HOUR = timedelta(hours=1) STDOFFSET = timedelta(seconds = -_time.timezone) if _time.daylight: DSTOFFSET = timedelta(seconds = -_time.altzone) else: DSTOFFSET = STDOFFSET DSTDIFF = DSTOFFSET - STDOFFSET class LocalTimezone(tzinfo): """ Timezone of the machine where the code is running """ def utcoffset(self, dt): if self._isdst(dt): return DSTOFFSET else: return STDOFFSET def dst(self, dt): if self._isdst(dt): return DSTDIFF else: return ZERO def tzname(self, dt): return _time.tzname[self._isdst(dt)] def _isdst(self, dt): tt = (dt.year, dt.month, dt.day, dt.hour, dt.minute, dt.second, dt.weekday(), 0, -1) stamp = _time.mktime(tt) tt = _time.localtime(stamp) return tt.tm_isdst > 0 def dt2DT(dt): "Converts Python datetime to Zope DateTime" try: # convert dt to local timezone ltz = dt.astimezone(LocalTimezone()) return DateTime(*ltz.timetuple()[:6]) except: return DateTime(dt.year, dt.month, dt.day, 0, 0, 0) def DT2dt(DT): """ Converts Zope DateTime to Python datetime, Zope DateTime is allways utc """ return datetime.fromtimestamp(DT.timeTime(), LocalTimezone()) -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science
