Why is there a discrepancy in my AliExpress tracking dates?

Hi All,

I started a dropshipping business a few months ago. I received a few orders early December & am a bit confused with the tracking information. For example, according to tracking in my AliExpress orders, the order departed from the country of origin on the 11th December. Global Order Tracking also advises the same date. But when I go to the AliExpress Standard Shipping website & track the order, I am advised it “Departed Origin Port” on the 15th December. Which do I believe ?
