Sometimes it is necessary to write some timed task scripts, a brief summary, memos.
1. Get current time
- python
Accurate to 0.001 seconds under Windows, and time accuracy under Linux 0.000001 second
>>> import datetime
>>> datetime.datetime.now()
datetime.datetime(2018, 5, 23, 17, 16, 33, 61000)
>>> print datetime.datetime.now()
2018-05-23 17:16:57.688000
- shell
date
Wed May 23 15:53:45 CST 2018
2. Time format
- python
>>> import datetime
>>> datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S ')
'2018-05-23 15:50:07'
- shell
date -I
2018-05 -23
[email protected]:/ # date "+%Y-%m-%d %H:%M:%S"
2018-05-23 15:51:29
3. Time addition and subtraction
- python
>>> t0 = datetime.datetime.now ()
>>> t1 = t0 + datetime.timedelta(seconds=600)
>>> print t0
2018-05-23 16:12:33.184000
>> > print t1
2018-05-23 16:22:33.184000
>>> t2 = t0-datetime.timedelta(days=2)< br />>>> print t2
2018-05-21 16:12:33.184000
- shell
Get the date of the previous Monday, which is the closest Monday, Not necessarily last Monday.
For example, today is Wednesday, then the previous Monday is the day before yesterday.
Also note that the busybox command on the Android system is a castrated version, and advanced parameters may not be supported.
date -d "last-monday" -I
2018-05-21
#Similarly, you can enter:
date -d "next -monday" -I
2018-05-28
#Yesterday
date -d "yesterday" -I
2018-05-22
