# TIMEZONE 时区支持 > ENGLISH DESCRIPTION > > The following is the support for various time zones and their corresponding UTC offset. > > For example, the AST timezone has a UTC offset of -4 hours, which means that to convert the time in this timezone to the UTC timezone, you need to subtract -4 hours. > > Calculation logic description > > If "2023-10-10 08:00:00 ast" > > So utc = "2023-10-10 08:00:00" - (-4) > > The mean utc = "2023-10-10 08:00:00" + 4 > > utc = "2023-10-10 12:00:00" > 中文描述 > > 以下是对各个时区的支持和对应的协调时区偏移量 > > 例如 ast 时区相对于协调时区 utc 的偏移量是 -4 小时,即如果要将这个时区的时间转换为 utc 时区的时间需要减去 -4 小时 > > 计算逻辑描述 > > 假设 "2023-10-10 08:00:00 ast" > > 那么 utc = "2023-10-10 08:00:00" - (-4) > > 即 utc = "2023-10-10 08:00:00" + 4 > > utc = "2023-10-10 12:00:00" ```json { "acdt": 37800, "acst": 34200,
