Time zones use hours and minutes offset from Coordinated Universal Time (UTC), most a whole number of hours, a few are offset by 30 or 45 minutes. Central Standard Time (CST) is UTC-6:00, and Central Daylight Time (CDT) is UTC-5:00, this time zone is called Central Time Zone (CT...
mysql的jdbc驱动的代码里会设置时区,这个时区是通过 TimeZone.getTimeZone(canonicalTimezone) 读取,其中 canonicalTimezone 是字符串, TimeZone.getTimeZone("CST") 返回-6时区,即美国的时区。Java中的CST时区问题坑 java.util.TimeZoneTimeZone.getTimeZone("Asia/Shanghai").getRawOffset() : 28800000 (单位:...
Coordinated Universal Time (UTC) is the primary time standard now, time zones around the world are expressed using offsets from UTC, UTC offset is the difference in hours and minutes from UTC, a time zone can be determined by adding or subtracting the number of UTC offset. Central Standard...
We use the IANA time zone database for calculating our time zone conversions. IANA is a well-known reputable source that coordinates and manages world timezone data. Most other sites use a static offset to convert between time zones. However, this method is prone to errors due to geopolitical...
我有一个挑战,后端数据总是以 UTC 时间存储。我们的前端数据始终以 CST 格式呈现。我无权访问这个“黑匣子”。 我想在我们的数据仓库中反映这一点。它位于欧洲 (CET)。所以“本地”转换将不起作用。 我想知道将 UTC 时间(我可以使用纪元毫秒或日期格式“2015-01-01 00:00:00”)准确转换为中央标准时间的最简...

而每15°的经线则称为该时区的中央经线，将全球划分为24个时区，其中包含23个整时区及180°经线左右...
2. Geographical regions - an area where a specific set of rules for finding the offset from UTC/Greenwich apply 里面提到说,ZoneId主要是用来做LocalDateTime和Instant的转换处理的,因为LocalDateTime使用了系统时区直接生成时间,对象信息内不包含时区信息,而Instant需要包含时区信息,所以在转换时需要...
下列範例說明GetUtcOffset(DateTime)搭配不同時區使用 方法,以及具有不同Kind屬性值的日期值。 using System; [assembly:CLSCompliant(true)] namespace TimeZoneInfoCode { public class TimeOffsets { public static void Main() { TimeOffsets timeoff = new TimeOffsets(); TimeZoneInfo cst = TimeZoneInfo....
