As a new ham, I'm running into this issue on eQSL, LOTW, and QRZ. How big of a "time window" does eQSL protocol allow or establish to accept time mismatches on QSLs? Not everyone's clock is accurate. I've had several QSL attempts where other operators had logged QSO times that were from a few minutes up to 4 hours off from the time that I had recorded on my handwritten sheets (that I triple check during logging and uploads).

Is there a log time 'window' within which the protocol accepts a one or five or fifteen minute deviation between the calls being entered by the two QSO operators?

eQSLs will match with QSO times +/- 60 minutes.

In addition to clocks not being accurate, some people log the time of the start time of the QSO, others log the end time, etc.
