TimePoint class

Represents a precise point in time on the blockchain.

A TimePoint uniquely identifies when a multisig transaction was initiated by combining the block height and the extrinsic index within that block. This is required by Substrate's multisig pallet to track and manage pending transactions.

The timepoint is automatically captured when the first approval is submitted and must be provided with all subsequent approvals to identify the specific transaction.

Example:

// TimePoint is automatically included in MultisigStorage
final storage = await MultisigStorage.fetch(...);
if (storage != null) {
  print('Transaction initiated at block ${storage.when.height}, '
        'extrinsic ${storage.when.index}');
}

Constructors
