dsal 将 Unix 时间戳转换为 DD/MM/YYYY HH:MM:SS 格式

将 Unix 时间戳转换为 DD/MM/YYYY HH:MM:SS 格式

原文:https://www . geesforgeks . org/convert-UNIX-timestamp-to-DD-mm-yyyy-hhmmss-format/

给定给定时间点的 Unix 时间戳 T (以秒为单位)，任务是将其转换为人类可读的格式(DD/MM/YYYY HH:MM:SS)

示例:

输入: T = 1595497956 输出: 23/7/2020 9:52:36 说明:在 unix 时间 T 有 1595497956 秒，所以它总共有 50 年 7 个月 23 天 9 小时 52 分 36 秒。

输入:T = 345234235 T3】输出: 9/12/1980 18:23:55

进场:

将给定的秒数除以一天中的秒数(86400)转换为天数，并存储剩余的秒数。
因为我们统计了自 1970 年 1 月 1 日以来的天数。因此，计算当前年份时要牢记闰年的概念。从 1970 年开始。如果年份是闰年，从天数中减去 366，否则减去 365。增加 1 岁。
重复步骤 2，直到天数少于 365 天(不能构成一年)。
在剩余天数(计算年份后的额外天数)中添加 1，因为剩余天数将为我们提供到前一天的天数，并且我们必须包括当前日期和月份计算。
将月数增加 1，并继续从额外天数中减去月数(请记住，闰年 2 月将有 29 天，否则将有 28 天)。
重复步骤 5，直到从额外的天数中减去一个月中的天数得到一个否定的结果。
如果额外天数大于零，则按月递增 1。
现在利用第一步的额外时间。
用额外时间除以 3600 计算小时，用剩余秒除以 60 计算分钟，剩余秒即为秒。

下面是上述方法的实现:
