Subject: [PATCH 7/7] Make test_change_epoch more robust.
|
||
|
|
|
||
|
|
The epoch is set by explicitly calling `mdates.set_epoch`, or implicitly
|
||
|
|
set to the default by `mdates.get_epoch` (which is also called when
|
||
|
|
converting datetimes.)
|
||
|
|
|
||
|
|
However, when running tests in parallel, there is no guarantee that any
|
||
|
|
other call to `[gs]et_epoch` might have been made to lock it in, so we
|
||
|
|
need to do that explicitly.
