Timezone Selector

[ABagram]

About

At the home page, inside the current-time-date div, the timezone should also be displayed, possibly above the current time or below the date in the format of GMT+8 (PST).

Appearance and Interactions

It will look like a regular span element (black background, white text) whose corners are rounded. When the user double clicks it, they can see a dropdown of options.

The structure for the timezone options should be

Local Time	Geographic Zones
GMT+8	Beijing, Chongqing, Hong Kong SAR, Urumqi

Important

Without the headers but replicate the alignment as if there are columns. Add an index to the right (similar to the single-character table of contents in contact lists).
