class documentation

class TZContextBase(object): (source)

Known subclasses: dateutil.test._common.TZEnvContext, dateutil.test._common.TZWinContext

Base class for a context manager which allows changing of time zones. Subclasses may define a guard variable to either block or or allow time zone changes by redefining ``_guard_var_name`` and ``_guard_allows_change``. The default is that the guard variable must be affirmatively set. Subclasses must define ``get_current_tz`` and ``set_current_tz``.

Class Method	`tz_change_allowed`	Class method used to query whether or not this class allows time zone changes.
