A clock that shows the visitor's own local time in large pixel digits, with a list of cities underneath and the current time in each. Every city is its own block in Fugte, so adding Sydney or dropping Berlin is drag and drop rather than an edit to the code, and each row carries a sun or a moon for whether it is day or night there plus how far ahead or behind the visitor it runs. Twelve or twenty-four hour format, the seconds, the date line and the colours all stay editable after the widget is on your page.
Customize opens this widget in the editor with its own controls already set up, so the wording, colours and content are form fields rather than code. Change what you like without an account. Sign in only when you want to keep it, and it saves as your own copy with its own embed line.
This line embeds the widget above, the same one running on this page, so it changes whenever this one does. Good for a quick try, not for something you want to control.

Building and embedding are free. Start from a blank editor instead if you would rather build something else.
QUESTIONS
The visitor's own. It reads the time zone from their browser, so a reader in Manila and a reader in Berlin each see their own local time in the large display, while the list underneath always shows the cities you chose.
Yes. Each city's time is worked out from its time zone at the moment the page is open rather than from a stored offset, so a city moves on and off daylight saving by itself and there is nothing to update twice a year.
Each city is one block and there is no fixed limit, though four or five rows is about as many as fits a sidebar before the list starts to crowd the clock above it.
Yes. It is a standard iframe, which every one of those platforms accepts in an embed or custom HTML block.
