关于 时区转换About Timezone Converter
安排跨国会议、排查海外用户日志、与远程团队协作时，经常需要知道“现在对方那边是几点”。本工具支持世界主要时区之间的任意时间转换，一次查看多个时区对照，让跨时区沟通不再靠心算。Scheduling international meetings, investigating overseas user logs or collaborating with remote teams all raise the question "what time is it for them right now?". This tool converts any time between the world’s major timezones and shows multiple zones side by side, ending mental timezone arithmetic.
使用方法How to Use
- 选择源时区并输入要转换的时间。Select the source timezone and enter the time to convert.
- 选择目标时区，工具立即给出换算结果。Select the target timezone; the converted time appears immediately.
- 如需对照多个时区，查看并列的时区时间列表。To compare several zones, view the side-by-side timezone list.
常见问题FAQ
UTC 是什么时区？What timezone is UTC?
UTC（协调世界时）是全球时区的基准，不实行夏令时。北京时间 = UTC+8，即比 UTC 早 8 小时。UTC (Coordinated Universal Time) is the global reference with no daylight saving. Beijing time = UTC+8, i.e. 8 hours ahead.
为什么有的时区相差半小时？Why are some zones offset by half hours?
时区偏移由各地区自行决定，印度（UTC+5:30）、尼泊尔（UTC+5:45）等按本地太阳时历史沿革取值，并非都是整小时。Offsets are set regionally; India (UTC+5:30) and Nepal (UTC+5:45) follow historical local solar time, so not all offsets are whole hours.
夏令时会自动处理吗？Is daylight saving handled automatically?
会。工具依据时区数据库规则换算，实行夏令时的地区（如欧洲、北美）在夏冬两季会自动使用不同偏移。Yes. The tool follows timezone database rules; regions observing DST (e.g. Europe, North America) automatically use different offsets in summer and winter.
