对UTC日期时间、本地日期时间使用此方法，并转换上午和下午

import pytz
from datetime import datetime

#UTC Time
print("UTC Date and time")
epoch: datetime =datetime.now().replace(tzinfo=pytz.utc)
print(epoch)

#local date and time
print("Local Date and time")
today = datetime.now()
local_time = today.strftime("%Y-%M-%d:%H:%M:%S")
print(local_time)

#convert time to AM PM format
print("Date and time AM and PM")
now = today.strftime("%Y-%M-%d:%I:%M %p")
print(now)

最快的方法是：

>>> import time
>>> time.strftime("%Y%m%d")
'20130924'

如果你经常使用panda，你可以使用Timestamp，它相当于Python的Datetime：

In [1]: import pandas as pd

In [2]: pd.Timestamp.now()
Out[2]: Timestamp('2022-06-21 21:52:50.568788')

只是时间：

In [3]: pd.Timestamp.now().strftime("%H:%M:%S")
Out[3]: '21:53:01'

获取当前日期时间属性：

import datetime

currentDT = datetime.datetime.now()

print ("Current Year is: %d" % currentDT.year)
print ("Current Month is: %d" % currentDT.month)
print ("Current Day is: %d" % currentDT.day)
print ("Current Hour is: %d" % currentDT.hour)
print ("Current Minute is: %d" % currentDT.minute)
print ("Current Second is: %d" % currentDT.second)
print ("Current Microsecond is: %d" % currentDT.microsecond)


#!/usr/bin/python
import time;

ticks = time.time()
print "Number of ticks since "12:00am, Jan 1, 1970":", ticks

对UTC日期时间、本地日期时间使用此方法，并转换上午和下午

import pytz
from datetime import datetime

#UTC Time
print("UTC Date and time")
epoch: datetime =datetime.now().replace(tzinfo=pytz.utc)
print(epoch)

#local date and time
print("Local Date and time")
today = datetime.now()
local_time = today.strftime("%Y-%M-%d:%H:%M:%S")
print(local_time)

#convert time to AM PM format
print("Date and time AM and PM")
now = today.strftime("%Y-%M-%d:%I:%M %p")
print(now)

您可以使用此函数获取时间（遗憾的是，它没有显示AM或PM）：

def gettime():
    from datetime import datetime
    return ((str(datetime.now())).split(' ')[1]).split('.')[0]

要获取稍后要合并的小时、分钟、秒和毫秒，可以使用以下函数：

小时：

def gethour():
    from datetime import datetime
    return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[0]

分钟：

def getminute():
    from datetime import datetime
    return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[1]

第二：

def getsecond():
    from datetime import datetime
    return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[2]

毫秒：

def getmillisecond():
    from datetime import datetime
    return (str(datetime.now())).split('.')[1]
