Hi, I'm trying unsuccessfully to configure a sqlcounter that is reset every
Sunday 0:00AM. Here's what i configured in radiusd.conf:

        sqlcounter weeklycounter {
                counter-name = Weekly-Session-Time
                check-name = Max-Weekly-Session
                reply-name = Session-Timeout
                sqlmod-inst = sql
                key = User-Name
                reset = weekly

                # For mysql:
                query = "SELECT SUM(AcctSessionTime - \
                 GREATEST((%b - UNIX_TIMESTAMP(AcctStartTime)), 0)) \
                 FROM radacct WHERE UserName='%{%k}' AND \
                 UNIX_TIMESTAMP(AcctStartTime) + AcctSessionTime > '%b'"
        }

After that, I did a radtest. From the resulting SQL trace, I notice "%b" is
expanded as 7 days earlier than today. For instance, when running radtest on
20 Nov 2007 1:16AM (a Tuesday), "%b" gets expanded to 13 Nov 2007 0:00AM (a
Tuesday too), which is not my desired outcome.

How do I configure a sqlcounter that is reset every Sunday midnight? Thanks
in advance, and sorry if there're any obvious mistakes that I have
overlooked.
