mclocks is an Open Source app that allows you to display multiple time zone clocks.

Having multiple time zone clocks available for viewing will be handy in various situations, like traveling and international meetings, etc.

Adding clocks involves setting the configuration file as config.json, which can be done via Notepad.

Here is an example of config.json for reference:

{
"clocks": [
{ "name": "NY", "timezone": "America/New_York" },
{ "name": "London", "timezone": "Europe/London" }
],
"formatDateTime": "MM-DD ddd HH:mm",
"localeDateTime": "en",
"opacity": 1,
"fontColor": "#fff",
"fontSize": 14,
"bgColor": "#151",
"onlyText": false,
"alwaysOnTop": false
}
