1、使用SSH 或者KVM登陆到主机系统界面，进入root账户
VMware vCenter Server Appliance 6.7.0.10000 Type: vCenter Server with an embedded Platform Services Controller Connected to service * List APIs: "help api list" * List Plugins: "help pi list" * Launch BASH: "shell" Command>
2、载入 BASH
输入shell
Command> shell Shell access is granted to root root@photon-machine [ ~ ]# root@photon-machine [ ~ ]# root@photon-machine [ ~ ]# root@photon-machine [ ~ ]# date Sat Jul 25 16:15:41 UTC 2020
3、先修改时区
找到新时区文件所在位置，在/usr/share/zoneinfo/$主时区/$次时区 目录下
# cd /usr/share/zoneinfo/Asia
root@photon-machine [ ~ ]# cd /usr/share/zoneinfo/Asia root@photon-machine [ /usr/share/zoneinfo/Asia ]# root@photon-machine [ /usr/share/zoneinfo/Asia ]# ls Aden Ashgabat Barnaul Choibalsan Dhaka Hebron Jakarta Kashgar Kuala_Lumpur Makassar Omsk Qyzylorda Seoul Tbilisi Tomsk Vientiane Almaty Ashkhabad Beirut Chongqing Dili Ho_Chi_Minh Jayapura Kathmandu Kuching Manila Oral Rangoon Shanghai Tehran Ujung_Pandang Vladivostok Amman Baghdad Bishkek Chungking Dubai Hong_Kong Jerusalem Katmandu Kuwait Muscat Phnom_Penh Riyadh Singapore Tel_Aviv Ulaanbaatar Yakutsk Anadyr Bahrain Brunei Colombo Dushanbe Hovd Kabul Khandyga Macao Nicosia Pontianak Saigon Srednekolymsk Thimbu Ulan_Bator Yangon Aqtau Baku Calcutta Dacca Gaza Irkutsk Kamchatka Kolkata Macau Novokuznetsk Pyongyang Sakhalin Taipei Thimphu Urumqi Yekaterinburg Aqtobe Bangkok Chita Damascus Harbin Istanbul Karachi Krasnoyarsk Magadan Novosibirsk Qatar Samarkand Tashkent Tokyo Ust-Nera Yerevan
备份时区文件
# mv /etc/localtime /etc/localtime-old
替换时区文件
# cp Shanghai /etc/localtime
# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
或者创建新时区链接文件，例如修改成亚洲-上海时区
# ln –s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

设置与硬件同步
# hwclock -w
重启机器生效
# reboot
4、修改时间的方法
使用# date -s修改日期
root@photon-machine [ ~ ]# date -s 2020-07-25 Sat Jul 25 00:00:00 CST 2020
使用# date -s修改时间
root@photon-machine [ ~ ]# date -s 17:10:15 Sat Jul 25 17:10:15 CST 2020
将当前时间和日期写入BIOS，避免重启后失效
# hwclock -w
