Adding a link to a time-zone converter tool to our website

Since we have people from many different timezones interacting with us, I'd propose to facilitate our website visitors by adding a link to https://www.timeanddate.com/worldclock/converter.html (or any other better tool) to:

• the footer of the page (relatively close to Support Hours?)
• Schedule a call webpage: https://cloud68.co/schedule-a-call

or somewhere you think makes sense.
