I'm located in Berlin but the protocol that I work for is split up all over the globe. So I it is always painful to calculate the time when we schedule a call for people in Sidney. Also there isn't a convenient way to find blocks by UTC.
What it does
It calculates the block number by the date range you specified.
How we built it
React, Etherscan API.
Challenges we ran into
Calculation of blocks in the future, since block time is not constant
Accomplishments that we're proud of
Finally a simple app that converts UTC to block number
What we learned
What's next for Decentralised Time
Pitch it to Rafael Suarez from Synthetix because he is looking for a feature like that for years.
