Function start_transaction_with_timestamp

pub fn start_transaction_with_timestamp(
    ctx: TransactionContext,
    timestamp: SystemTime,
) -> Transaction

The transaction needs to be explicitly finished via Transaction::finish, otherwise it will be discarded. The transaction itself also represents the root span in the span hierarchy. Child spans can be started with the Transaction::start_child method.
