First, Introduction
Android Linux platform based open source mobile OS.
Second, the principle
Since Linux, it should support a variety of Linux command line, highly configurable, but the experiment found that Android is a highly castrated version of Linux, many commands are not supported, such as the Rdate command (Network Synchronization Time command). Since I don't support it, I'm not going to get him to support it.
Third, BusyBox
BusyBox is a single executable implementation of standard Linux tools. BusyBox contains a few simple tools, such as Cat and Echo, and includes larger, more complex tools such as grep, find, Mount, and Telnet. Some people call BusyBox the Swiss Army Knife in the Linux tool. Simply put, BusyBox is like a large toolbox that integrates many of the tools and commands that compress Linux.
Four, download BusyBox
A rough search on the internet, a lot of tutorials are taught you to cross compile BusyBox, but I found this has been compiled, direct download into the system can be.
Can download to this website, also can download to the attachment:

Note that you must already have root access to the phone and have file management software such as root manager.
Five, push into the mobile phone
1, mobile phone: With the root manager, such as software, hanging in for writable
2, Computer: Open the command line (start-> run-> input cmd, if it is Vista or Win7 Run as Administrator)
3. Computer: ADB push Busybox/system/app
4, with the root manager into the/system/app, find BusyBox cut to/system/sbin
5. Computer: adb shell
6. Computer: su
7. Computer: chmod 777/system/sbin/busybox
After a few steps above, have finished putting the busybox into the system.
You can knock at the command line on your computer: BusyBox, a supported command line will appear. The following figure
Vi. using Rdate Network synchronization time
1, open the mobile phone GPRS or WIF, anyway, mobile phone connected to the network can be.
2, this step is tested, not necessary, computer input command: BusyBox rdate-p 203.129.68.14, will print the current time
3, the input command, the network time synchronization to the mobile phone time: BusyBox rdate-s 203.129.68.14
