Just going to add for emphasis - as the sms receiving party
the most useful date/time information is when did the sender send
the sms. Inexplicably, Android/AOSP seems to throw that data away (because it might be inaccurate).
The when phone received date/time stamp data, that AOSP chooses to use, is of little value to the recipient because they will know when they read the sms. The sender
has sms received receipts
to learn when the receiving phone acknowledged receipt.
