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?

Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
