Quick question. Is it common or normal for the time stamps on imessages to be off by a minute? For example I sent a message at 11:39pm and the response received directly after that message was time stamped at 11:38pm. What would cause there to be a 1 minute discrepancy? Is it just a glitch, or does the time stamp come back based on the senders phone and what the time was when they sent it?
