雪豹有了新的功能,可以根据你的所在地自动设定时区。是这项功能可以使用,打开系统设置,点击“Date and Time”,在时区标签下面,选中“Set time zone automatically by location” 选项,地图变灰,然后你的MAC就会通过 CoreLocation决定你的当前位置了

总的来说,你的MAC没有GPS,所以代替这者工作的是核实存在的WIFI网络通过当地的数据中心。所以他只在你的AIRPORT打开时才工作,但并不是你一定要通过它来连接网络。当然在WIFI很多城市里,定位起来更精确。

如果你连接了GPS到你的MAC,并且它被MAC OSX认出,CoreLocation会使用它来定位。这意味着在附近有WIFI并不是必须的,你需要保证有GPS信号。


当你带着你的MAC旅游时,时区会自动跟新到你的所在地。



其他程序也可以使用CoreLocation。例如Google Latitude 要求进入你的所在地,这样可以与你的朋友分享。然而,这种程序始终会要求进入你的本地信息,一些人可以看见,例如隐私,以及安全风险。要想完全不使用CoreLocation功能,在系统设置的安全选项选中“Disable Location Services”。

Snow Leopard has the ability to automatically set your time zone based on your location. To enable this, go to System Preferences and click on the “Date and Time” section. Under the Time Zone tab, check the “Set time zone automatically by location” option. The map should become greyed out, and your Mac should determine your current location using CoreLocation.

Generally your Mac won’t have GPS, so instead this works by checking the visible Wi-Fi networks against a database of their locations. As a result this only works when your AirPort is turned on, but it isn’t necessary for you to be connected to the internet through it. Of course this also works much more accurately in urban areas where there are lots of Wi-Fi networks around.

If you have connected a GPS device to your Mac and it is recognised by Mac OS X, CoreLocation should switch over to using that. This means that having nearby Wi-Fi networks is not an issue, but you do need to make sure you have GPS signal.

Now when you travel with your Mac, the time zone should automatically update to your new location.

Other applications can also use CoreLocation. For example, Google Latitude asks for access to your location so it can share it with your friends. While an application must always ask your permission for access to your location information, some people still see this as a bit of a privacy and security risk. To disable CoreLocation completely, go to the Security section of System Preferences and check the “Disable Location Services” checkbox under the General tab.
