Python Time Module Temporal conversion

Get current time

Gets the current time stamp

time_now = int(time.time())  #时间戳  # 1529461333

Format time

import timecurrent_time=time.strftime(‘%Y-%m-%d %H:%M:%S‘,time.localtime(time.time()))current_hour=time.strftime(‘%H‘,time.localtime(time.time()))#输出格式: ‘2018-06-20 10:20:19‘

Database DateTime format support.

current_time=time.strftime(‘%Y-%m-%d %H:%M:%S‘,time.localtime(time.time()))#在数据库中，字段可以是varchar而不是datetime

Convert Timestamp to TIME

a=1490931508time.strftime(‘%Y-%m-%d %H:%M:%S‘, time.localtime(a))

Convert time to time stamp

c=‘2017-03-31 11:38:28‘d=time.strptime(c,‘%Y-%m-%d %H:%M:%S‘)time.mktime(d)

JSON serializes a datetime field in MySQL

from bson import json_utilimport jsonjson.dumps(anObject, default=json_util.default)json.loads(aJsonString, object_hook=json_util.object_hook)

Time Operation:

Method One:

        time1 = datetime.datetime.now()        time2 = datetime.datetime.now()        seconds = (time2 - time1).seconds        print ‘seconds‘,seconds

Method Two:

        #先获得时间数组格式的日期        oneDayAgo = (datetime.datetime.now() - datetime.timedelta(days = 1))        #minutes, days, months,        #转换为时间戳:        timeStamp = int(time.mktime(oneDayAgo.timetuple()))          #转换为其他字符串格式:        time1 = oneDayAgo.strftime("%Y-%m-%d %H:%M:%S")        time2 =  host.update_time        if time2 > time1:            print "正常"        else:            print "未上报"
