https://github.com/apache/incubator-ponymail/issues/84
Example of an early imported mail.
The source [1] has the following date:
Date: Sun, 31 May 2015 22:19:41 -0000
The Permalink page [2] has the following info:
Date: 2015-05-31 23:19 (-0000)
This is clearly wrong, but may be a GUI-only issue
The summary info [3] shows the following:
mid":
"fba1fa838d345c3b30b3db543425419a85ffde5f89ed2278063cf0c6@1433110781@<notifications.commons.apache.org>",
"date": "2015/06/01 00:19:41",
epoch": 1433110781,
The epoch value corresponds to 2015-05-31 22:19:41 UTC
So the epoch agrees with the source mail.
The date in the mbox record is two hours adrift, and is the reason why the
message appears in the wrong month.
