Transaction Timestamps

Kaspa transactions do not contain timestamps. Instead, transactions contain the DAA (Difficulty Adjustment Algorithm) score. The DAA score can be translated into an approximate timestamp by using the RpcClient.getDaaScoreTimestampEstimate RPC method.

This method accepts a list of DAA scores and returns a list of approximate timestamps corresponding to each DAA score.

Processing Timestamps

Transaction-related events contain a TransactionRecord interface that includes the unixtimeMsec? property.

This property is always undefined if the transaction occurs in real time. There is no need to convert the DAA score to a timestamp if you are processing live transactions; you can simply capture the current system time on the client side.

However, if the transaction is of the discovery type, the unixtimeMsec property will contain the approximate timestamp of the transaction.

This behavior is subject to change in the future, so it is recommended to always follow these steps:

1. If the transaction is not of the discovery type, use the current system time.
2. If the transaction is of the discovery type and the unixtimeMsec property is undefined, use the RpcClient.getDaaScoreTimestampEstimate method to get the approximate timestamp for the transaction.
