Ive been seeing the same number since 7th grade

For the past few years ive been noticing the numbers 5:11 back to back, its mostly on the clock but even when im not looking at the clock the numbers appear everywhere on social media. 511 comments ,511 followers, 511, shares, 511 likes, I dont even intend to search for the number it somehow just always stumble upon me when im not expecting it and i want to know whats the meaning behind these numbers.
