В 1919 году в Ростове-на-Дону буквально не знали, сколько времени
Нет, это не шутка. Дело в том, что до революции в Ростове-на-Дону ежедневно в 8 часов утра производили проверку времени с Петроградом, а к 1919 году эта система распалась.
Но как революция сломала часы, а Донской университет (ныне ЮФУ) стал центром синхронизации времени на Юге России? Кого звали «живым хронометром» Ростова?

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
In recent times, Telegram has gained a lot of popularity because of the controversy over WhatsApp’s new privacy policy. In January 2021, Telegram was the most downloaded app worldwide and crossed 500 million monthly active users. And with so many active users on the app, people might get messages in bulk from a group or a channel that can be a little irritating. So to get rid of the same, you can mute groups, chats, and channels on Telegram just like WhatsApp. You can mute notifications for one hour, eight hours, or two days, or you can disable notifications forever.
