Splits the given C{datetimeString} into tokens, finds the regex
patterns that match and then calculates a C{struct_time} value from
the chunks.
If C{sourceTime} is given then the C{struct_time} value will be
calculated from that value, otherwise from the current date/time.
If the C{datetimeString} is parsed and date/time value found, then::
If C{version} equals to L{VERSION_FLAG_STYLE}, the second item of
the returned tuple will be a flag to let you know what kind of
C{struct_time} value is being returned::
0 = not parsed at all
1 = parsed as a C{date}
2 = parsed as a C{time}
3 = parsed as a C{datetime}
If C{version} equals to L{VERSION_CONTEXT_STYLE}, the second value
will be an instance of L{pdtContext}

Default set of constants for parsedatetime.
If PyICU is present, then the class will first try to get PyICU
to return a locale specified by C{localeID}. If either C{localeID} is
None or if the locale does not exist within PyICU, then each of the
locales defined in C{fallbackLocales} is tried in order.
If PyICU is not present or none of the specified locales can be used,
then the class will initialize itself to the en_US locale.
if PyICU is not present or not requested, only the locales defined by
C{pdtLocales} will be searched.

GetReturn a date/time tuple based on the giving source key
and the corresponding key found in self.re_sources.
The current time is used as the default and any specified
item found in self.re_sources is inserted into the value
and the generated dictionary is returned.
