To keep the hardware clock sane and the time correctly displayed by multiple systems they need to agree on which timezone the hardware clock is kept at.
Setting the hardware clock to local time with multiple systems is broken if the time zone has daylight saving shifts. It cannot work, as each system will apply the shift without knowing another already did it.
Windows 7 and later versions support setting the hardware clock to UTC through a registry setting. But with Windows XP the cleanest way is to use the UTC timezone or disable daylight saving shifts, or use NTP on each system to keep the system clock correct.
