直接比较Javascript ISO日期字符串是否安全? [英] Is direct comparison of Javascript ISO Date Strings safe?
问题描述
像这样直接比较ISO日期字符串是否安全:
Is it safe to directly compare ISO Date Strings like this:
"2018-03-16T18:00:00.000z">"2018-04-16T18:00:00.000z"//否
似乎只要使用前导零(正确的ISO格式),此比较就很安全,并且不需要将值转换为日期对象.我在俯视什么吗?
It seems as long as leading zeros are used (proper ISO formatting) this comparison is safe and there is no need to convert the values to Date Objects. Am I overlooking something?
推荐答案
使用给定格式的 ISO8601 时间,
2018-03-16T18:00:00.000Z

您可以使用直接字符串比较,因为给定的时区是一个
you could use a direct string comparison, because the given time zone is a
世界标准时间(UTC)
如果时间以UTC表示,则在时间后直接添加一个Z,不能带空格.Z是零UTC偏移量的区域标记."09:30 UTC"因此,表示为"09:30Z".或"0930Z"."14:45:15 UTC"将为"14:45:15Z"或"144515Z".
Coordinated Universal Time (UTC)
If the time is in UTC, add a Z directly after the time without a space. Z is the zone designator for the zero UTC offset. "09:30 UTC" is therefore represented as "09:30Z" or "0930Z". "14:45:15 UTC" would be "14:45:15Z" or "144515Z".
