time

```python

time.time()    #UTC 기준 초단위 실수형 리턴

time.localtime()    #초단위 실수형 리턴값을 연,월,시 등의 time.struct_time(투플)로 리턴

time.asctime()    #time.struct_time을 보기 좋은 형태로 리턴

time.ctime() == time.asctime(time.localtime(time.time())) 

time.strftime('형식 포맷 코드', time.localtime(time.time()))

time.sleep()

```

 

 

date

```python

>>> import datetime

>>> datetime.datetime.now()

datetime.datetime(2017, 11, 12, 8, 12, 50, 236423)

>>> datetime.datetime.now().strftime('%y%m%d-%H%M')

'171112'

>>> (datetime.now() - timedelta(minutes=20)).isoformat(timespec='seconds')

'2018-07-25T00:32:17'

 

>>> datetime.date.today()

datetime.date(2017, 11, 12)

>>> datetime.date.today().strftime('%y%m%d')

'171112'

 

>>> str_date = '2004/03/30'

>>> date = datetime.strptime(str_date, "%Y/%m/%d")

```

 

```py

def get_utc():

    hours = int(time.localtime().tm_gmtoff / 3600)

    minutes = time.localtime().tm_gmtoff % 60

    return "+{0:0>2}:{1:0>2}".format(hours, minutes)

```
