Was working for cross-region company and got use to an tiny App that can handily display multiple times from different time-zones (a nice country flag followed by the time) in the macOS menu bar. Today when I tried to reinstall it on another Mac, following filling of email, then country of Australia with post code, it prompts for FREE for "lock down". Not sure how long has it been and will it last for. Grab one if you need. Although free you still get an activation code sent to the email you typed.
p.s. Apple Silicon users head up: it does not support M1 (Arm64) architecture yet, but it does run smoothly through translation using Rosetta 2.
Hit the "Download DMG" rather than AppStore link as I encountered "app not existed in the AppStore" and manual download was where it offered it for free for me. Saved a fiver. Thanks to the developer.
