????Linux默認情況下使用UTC格式作為標準時間格式，如果在Linux下運行程序，且在程序中指定了與系統(tǒng)不一樣的時區(qū)的時候，可能會造成時間錯誤。在Server版中，需要通過tzconfig來修改時區(qū)信息了。使用方式(如將時區(qū)設置成Asia/Chongqing)：?

? ? ok，這里我們已經將時區(qū)選成了Asia/Shanghai了，但是我們還需要做如下的操作

????

root@nao:~#?cp?/usr/share/zoneinfo/Asia/Shanghai?/etc/localtime

? ?然后我們執(zhí)行時間同步命令：

????

ntpdate?192.168.1.100

? ?然后我們可以查看我們的時間已經調整回來了，如果需要定時同步的話，要在定時任務中加一條同步的定時任務就可以了。
