[Users] DST and accounting

Hello, I have sent this a while ago but it did not come, so if you are getting the mail for the second time sorry. You may be aware of the accounting problem with Daylight Savings Time. Currently in Radius accounting we have a timestamp of the event acoording to system clock (i think). So if a call starts soon before a daylight saving change and ends soon after it, it may have too big or negative duration, depending on whethere the clock moved forward or backward. Is there a way to make accounting take notice of that (maybe accounting in gmt+offset or something?) Any ideas appreciated, as you know DST is comming soon for europe at least. Dimitar
