Even Amazon programming has no clue on this … example

This item’s label was purchased at 8:24am CENTRAL TIME and Amazon reported as 8:24am Pacific Daylight Time which is a 2 hour discrepancy.
The USPS in possession time of 11:23am and the Departed Post Office time 3:02pm are both CENTRAL TIME are both reported by Amazon as the same two times but again as Pacific Daylight Time which would be wrong (time zone wise).
Here is the interesting part … the Arrived at USPS Regional Origin Facility is 11:16pm CENTRAL TIME is reported by Amazon as 9:16pm Pacific Daylight Time which means both system match at this point.
We do everything before 2:30pm Central Time (this is 30 minutes before our little post office closes for the day) which puts us 11 1/2 hours before Amazon’s 11:59pm Pacific Time of the same day. Our issues normally fall on USPS problems and not Amazon because of the parameters we have to work with.
However, with that being said … it is always easy to find discrepancies between Amazon and USPS reporting of the times and the scans of the packages’ times. We have seen Amazon use Greenwich Mean Time.
No matter what Amazon means with “ship by” and “confirm by” … if you ship (with carrier scan) and confirm by 8:pm your time zone on the last day listed in the “ship by” section, then you meet or exceed Amazon order shipping expectations.
