    Oct 2021 - Nov 2021 (2 months)
    The Time Cog library aims to facilitate the management of time related data in solidity. The library is built relying on conversion algorithms by Howard Hinnant documented at Howard's Github Pages. The algorithm based approach allows the functions to minimize gas consumption since it avoids running loops or lookup tables in solidity. The library supports negative unix timestamps and negative time deltas, in the management of negative values the value doesn't rely on the casing of uint to int and viceversa which also, according to our testing, helps to reduce gas consumption.
