Detailed Description

template<uint16_t IntervalMs, uint64_t EpochMs>
class sysio::chain::block_timestamp< IntervalMs, EpochMs >

This class is used in the block headers to represent the block time It is a parameterised class that takes an Epoch in milliseconds and and an interval in milliseconds and computes the number of slots.
