Simple and efficient timestamp representation. The main objective being interoperability with OCaml Corekernel.Timens.
A significant part of the code has been adapted from the OCaml Core_kernel implementation.
The set of supported timezones can be filtered using the TIMENS_TZ_FILTER
environment variable, e.g.:
bash
TIMENS_TZ_FILTER="London|New_York|Hong_Kong|Tokyo|GMT" cargo build
