Default [Q] Detailed delivery reports on Spica with real time?

Hi guys

I'm using our good old Galaxy Spica with CyanoGen 6.3. My issue is that I need an accurate (to the minute) timestamp when an SMS was sent and delivered. So far I have tried Go SMS, Handcent SMS, Delivery Reports+ and few other apps - the first two show delivery report time equal to sending time even if the actual offset is like 5 minutes (tested by sending messages to my other phone while it was off) and the third app didn't even want to work.

So my question is: does anyone know either an app or hack that would allow me to get accurate delivery report times?
