Contact Pattern
The Contact Pattern (style 1) displays your current local time in its top-right corner. For users from other countries, this time will be shown adjusted to their time zone.
To set your time zone, after adding the pattern, click on the “Local time” label in its top-right corner and, in the editor’s right sidebar, specify your time zone in the “HTML Anchor” field.

A list of time zones can be found on Wikipedia.
