It was March 25th, 2021, tree years ago already, during Jack Dorsey's testimony before the Members of the House Energy and Commerce Committee on misinformation, Moscow Time became a Bitcoin meme spawned by cybersecurity researcher Chris Vickery. He started the meme with his tweet[1] asking what time zone Jack was testifying from as his "clock" said 1952. He clarified in a further tweet[2] that the clock must be set to current Moscow time, refusing to believe otherwise.
Today, it's 1501, everywhere, not just in Moscow ;)
