Duration.toString介绍

[英]A string representation of this duration using ISO-8601 seconds based representation, such as PT8H6M12.345S.

The format of the returned string will be PTnHnMnS, where n is the relevant hours, minutes or seconds part of the duration. Any fractional seconds are placed after a decimal point i the seconds section. If a section has a zero value, it is omitted. The hours, minutes and seconds will all have the same sign.

Examples:

"20.345 seconds"                 -> "PT20.345S 
"15 minutes" (15 * 60 seconds)   -> "PT15M" 
"10 hours" (10 * 3600 seconds)   -> "PT10H" 
"2 days" (2 * 86400 seconds)     -> "PT48H"

Note that multiples of 24 hours are not output as days to avoid confusion with Period.
[中]此持续时间的字符串表示，使用基于ISO-8601秒的表示法，如PT8H6M12。345S。
返回字符串的格式为PTnHnMnS，其中n是持续时间的相关小时、分钟或秒部分。任何小数秒都放在秒部分的小数点i之后。如果一个部分有一个零值，它将被忽略。小时、分钟和秒都有相同的符号。
示例：

"20.345 seconds"                 -> "PT20.345S 
"15 minutes" (15 * 60 seconds)   -> "PT15M" 
"10 hours" (10 * 3600 seconds)   -> "PT10H" 
"2 days" (2 * 86400 seconds)     -> "PT48H"

请注意，24小时的倍数不输出为天，以避免与周期混淆。
