When trying to send an SMS and send back one, the timestamp shown in log is hours into the future. Not a Gaia issue. I/Gecko ( 2614): SmsDatabaseService: Going to store {"delivery":"sent","sender":null,"receiver":"+886912345678","body":"Hello!","timestamp":1332999591630,"id":11} I/Gecko ( 2614): SmsDatabaseService: Going to store {"delivery":"received","sender":"+886912345678","receiver":null,"body":"Hello back!","timestamp":1333057268000,"id":12} It has been reported people on different timezone sees different offsets. Gaia issue: https://github.com/andreasgal/gaia/issues/1074#issuecomment-4797291
It looks a lot like the timezone offset is added at least twice to the timestamp. I bet the RIL worker and/or the conversion of timestamp to Date object to timestamp to Date object is messing it up somewhere.

Summary: Received SMS has timestamp offsets hours into the future → B2G SMS: Timezone offset is added to timestamp at least twice
Yeah, good catch. the received message is 16 hrs and 76.37 seconds ahead of the sent message. 76.37 secs is reasonable typing time of mine during the manual test.
I'd like to look into this.
Go for it! Thanks!
