From 37628ffd977d8233ad02d482c5d70a0cf9719dce Mon Sep 17 00:00:00 2001
From: Vincent Ambo <tazjin@google.com>

Subject: [PATCH] date: add "dottime" format
Adds dottime (as defined on https://dotti.me) as a timestamp format.
This format is designed to simplify working with timestamps across
many different timezones by keeping the timestamp format itself in
UTC (and indicating this with a dot), but appending the local offset.
