Mac windows time synchronization problem)

By default, Windows XP and MacOSX treat the clock of the PC's CMOS record differently.

WINXP treats the clock as the local time, that is, the CMOS time is Beijing time.
MacOSX treats the clock as the Coordinated Universal Time (UTC) world standard time, that is, Greenwich Mean Time (GMT) Greenwich Mean Time.

Therefore, if you select Beijing time as the local time zone for both MacOSX and WINXP, once you connect to the Internet and synchronize the time, the time will be inconsistent.

We can change the default CMOS treatment mode of Windows XP to UTC, that is, it is consistent with MacOSX. The method is as follows:

In the registry, add HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet \ Control \ timezoneinformation \ realtimeisuniversal. The type is REG_DWORD and the value is 1. You can.

In this way, you set the local time zone to Beijing time in Windows XP and MacOSX. After the time synchronization between windows and MacOSX, the other side will not be affected.
