时间戳和日期字符串快速转换

背景

开发中经常会遇到时间戳和日期字符串转换的问题。

本文给出一种时间格式快速转换的解决方案，提升开发效率。

使用方法

先来体验一下如何使用

查询当前时间

时间戳转日期格式

日期转时间戳

实现脚本

使用 python 脚本实现

# encoding=utf8
import time
import sys

useage = """
    useage: time （时间戳|时间字符串）

        eg:
            ➜  time 1553671750        
            2019-03-27 15:29:10

            ➜  time "2019-03-27 15:29:10"
            time_format: 2019-03-27 15:29:10
            seconds: 1553671750     millseconds: 1553671750000

            ➜  time "2019-03-27"
            time_format: 2019-03-27
            seconds: 1553616000     millseconds: 1553616000000
"""

if __name__ == "__main__":
    if len(sys.argv) == 2:
        try:
            timeStr = sys.argv[1]
            if timeStr.isdigit():
                if len(timeStr) > 10:
                    timeStruct = time.localtime(int(sys.argv[1]) / 1000)
                else:
                    timeStruct = time.localtime(int(sys.argv[1]))
                print "timestamp:", timeStr
                print "time_format:", time.strftime("%Y-%m-%d %H:%M:%S", timeStruct)
            elif timeStr.find("-") > 0 and timeStr.find(":") > 0 and len(timeStr) == 19:
                timeStruct = time.strptime(timeStr, "%Y-%m-%d %H:%M:%S")
                result = int(time.mktime(timeStruct))
                print "time_format:", timeStr
                print "seconds:", result, "\tmillseconds:", result * 1000
            elif timeStr.find("-") > 0 and len(timeStr) == 10:
                timeStruct = time.strptime(timeStr, "%Y-%m-%d")
                result = int(time.mktime(timeStruct))
                print "time_format:", timeStr
                print "seconds:", result, "\tmillseconds:", result * 1000
            else:
                print useage
        except:
            print "error", useage
    elif len(sys.argv) == 1:
        nowTime = int(time.time())
        timeStruct = time.localtime(nowTime)
        print "current time_format:", time.strftime("%Y-%m-%d %H:%M:%S", timeStruct)
        print "seconds:", nowTime, "\tmillseconds:", nowTime * 1000
    else:
        print useage

生成可执行文件

Python 脚本可使用 pyinstaller 模块很方便的打包成可执行文件(使用方法参看pyinstaller官网)

pyinstaller -F time.py

如果您有类似场景，这种方式将很大程度提升效率哦
