SportsFilter has been misreporting the time on posts and comments since the U.S. sprang forward, reporting times in CST instead of CDT.
To fix the problem, I wrote a few lines of ColdFusion code to set a tzid variable to the proper timezone identifier:
<cfset tzinfo = GetTimeZoneInfo()>
<cfset tzid = "CST">
<cfif tzinfo.isDSTOn IS "True">
<cfset tzid = "CDT">
