It looks like time zone is not in that string, I am asking developers
of Silence application about that.

Namely, Silence replaces default Android/Replicant/LineageOS SMS
application and enables encryption, so that network providers cannot
(easily) spy on messages. Yet in sales handling and customer
relationship handling, all messages should be somehow visible or
accessible to future sales managers handling such customers and
new sales.

I hope that Silence developers will answer about the format, and if
it is UTC time.

Thanks.
