:
Cumulus timestamp related primitives.
Provides a InherentDataProvider
that should be used in the validation phase of the
parachain. It will be used to create the inherent data and that will be used to check the
inherents inside the parachain block (in this case the timestamp inherent). As we don't have
access to any clock from the runtime the timestamp is always passed as an inherent into the
runtime. To check this inherent when validating the block, we will use the relay chain slot. As
the relay chain slot is derived from a timestamp, we can easily convert it back to a timestamp
by multiplying it with the slot duration. By comparing the relay chain slot derived timestamp
with the timestamp we can ensure that the parachain timestamp is reasonable.
