You'll have to ask Congress.  The U.S. daylight-saving rules were 
changed by H.R. 6, Energy Policy Act of 2005, Section 110.  Evidently 
one of your hosts has old tables, and you need to upgrade them to the 
rules that were put in place in the tz database release 2005l, dated 
2005-08-22.  While you're at it, I suggest updating to the current tz 
version (2014b).
