Currently there is an incentive to post a question in a specific minute of the hour (the first, for the record). In order to do, I posted, Any GPIO library that supports I2C multi-master mode? which was around 15 seconds past the top of the hour (which was 7pm in New York) according to my nptd
synchronised PC. After waiting patiently for a day my reaction to the gamification on SE had still not earned it's reward - and I'm as Mad as a Hatter (and not a "Hero of Time") but not so Mad I cannot wait until 7pm in Tokyo...
Question: just how accurate is the Stack Exchange time-keeping?
