	Exception thrown when timestamp conversion functions receive/produce invalid google::protobuf::Timestamp accrording to IsValid or otherwise lead to undefined behavior due to integer overflow. More...
class	ugrpc::DateConversionError
	Exception thrown when date conversion functions receive/produce invalid google::type::Date accrording to IsValid or otherwise lead to undefined behavior due to integer overflow. More...
class	ugrpc::DurationConversionError
	Exception thrown when duration conversion functions receive/produce invalid google::protobuf::Duration accrording to IsValid or otherwise lead to undefined behavior due to integer overflow. More...

Functions
bool	ugrpc::IsValid (const google::protobuf::Timestamp &grpc_ts)
	Checks if google::protobuf::Timestamp contains a valid value according to protobuf documentation.
template<class Duration>
google::protobuf::Timestamp	ugrpc::ToProtoTimestamp (const std::chrono::time_point< std::chrono::system_clock, Duration > &system_tp)
	Creates google::protobuf::Timestamp from std::chrono::time_point.
