hmm, got a reference for that?
http://www.mythtv.org/wiki/ACPI_Wakeup#BIOS_setup says

"If supported by your environment, set the time to UTC (Coordinated
  Universal Time); UTC is the most desirable option because translation
  to local time is not required and daylight saving time is
  automatically handled. If UTC is not supported in your environment you
  will need to recalculate the time before you write it to the RTC."

which matches my prior knowledge (1st and 2nd hand)
