Acct nt

The acct_nt lock can be found on T2 NPCs.

In order to provide an answer to the acct_nt lock (either as integer or string), you need to read through your "accts.transactions" and add/subtract the values between two specitic timestamps.

acct_nt will ask you for information about your transaction history in one of three basic forms:
 * 1) Value of a large deposit/withdrawal near
 * 2) Net of transactions between and
 * 3) Amount earned/spent between and with/without memos.

Note that in the second case the answer can also be negative.

acct_nt will provide the timestamps for two specific transactions in the history, but they are only accurate to the minute. If several transactions happened within that same minute, acct_nt could be referring to ANY of them.

acct_nt picks two transactions, for example your 4th and 10th transaction. It then gets the timestamps of those, adds a small random amount of time (a few seconds) to the end time (and subtracts from the start time), then truncates the seconds off, and presents you those timestamps.

That means, timestamps given by acct_nt locks are calculated differently than those in your transaction log. And that means, if you have multiple transactions on the endpoint timestamps, it almost certainly doesn't want all of them. Also, the endpoint can be the wrong minute (if it was 38 minutes 58 seconds internally, and it adds 3 seconds, it will display a timestamp with 39 minutes.)
