Subject: [PATCH] gcal-window: datetime settings shortcut
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Shortcut is added so that time-related system settings can be easily
accessed. See #1023

The code is largely just a copy-paste of the code that opens the
"Online Accounts…" menu.

Fixes #1023
