Hello, the default queries for mysql log Acct-Delay-Time into the columns acctstartdelay and acctstopdelay, respectively. They leave the timestamps for acctstarttime and acctstoptime at %S. For a non-zero delay, this means that a database reader needs to do math to get the start and stop times. It is rather unintuitive that a database user needs to calculate the *actual* event times manually by substracting the values. This is something that MySQL can easily do on its own at INSERT or UPDATE. Is there a specific reason why the two are kept separate? If not, I'll merrily volunteer to update the default query set to do so; I'll do this for my deployment's custom queries anyway. This would also make the two columns for delay time obsolete. Any thoughts on this?
