如何在Python中添加一分钟到Hive时间戳格式

Question

I wanted to add a minute to the date which is in the Hive timestamp format of 'YYYY-MM-DD HH24:MI:SS.FF6' using Python

Example:1) 2015-01-15 08:59:16 date after adding a minute should become 2015-01-15 09:00:16 2)

For this, I got the minute part from the date and added 1 to it with a modulo 60: str((int(csvRowArray[1][10:12])+ 1)%60)

Here csvRowArray[1] is the date in string format.

The problem comes when the minute is 59, although it resets the minute part to 0, the hour part doesn't increase. This should also work when the hour is 23:59 and we add a minute, the date should change.Or if the date is at the end of the month and the hour is 23:59 then even the month should change!

Is there a function in Python to read the date in Hive timestamp format and add a minute to it?

Answer 1

It will help if you can convert the object into DateTime instances as that will allow you to manipulate the time directly using timedelta . Taking your example of '2015-01-15 08:59:16'

from datetime import datetime as dt
from datetime import timedelta
a='2015-01-15 08:59:16'
dt_obj = dt.strptime(a, '%Y-%m-%d %H:%M:%S')
dt_with_one_more_min = dt_obj + timedelta(minutes=1)
print('original time = {}'.format(dt_obj))
print('new time = {}'.format(dt_with_one_more_min))

This will give the following result:

original time = 2015-01-15 08:59:16
new time = 2015-01-15 09:00:16

My example is with minutes, but you can try other modifications too with timedelta and it will work.
