26. Convert Epoch Times to Timestamps

Write a Pandas program to convert integer or float epoch times to Timestamp and DatetimeIndex.

Sample Solution:

Python Code :

import pandas as pd
dates1 = pd.to_datetime([1329806505, 129806505, 1249892905,
                1249979305, 1250065705], unit='s')
print("Convert integer or float epoch times to Timestamp and DatetimeIndex upto second:")
print(dates1)
print("\nConvert integer or float epoch times to Timestamp and DatetimeIndex upto milisecond:")
dates2 = pd.to_datetime([1249720105100, 1249720105200, 1249720105300,
                1249720105400, 1249720105500], unit='ms')
print(dates2)

Sample Output:

Convert integer or float epoch times to Timestamp and DatetimeIndex upto second:
DatetimeIndex(['2012-02-21 06:41:45', '1974-02-11 09:21:45',
               '2009-08-10 08:28:25', '2009-08-11 08:28:25',
               '2009-08-12 08:28:25'],
              dtype='datetime64[ns]', freq=None)

Convert integer or float epoch times to Timestamp and DatetimeIndex upto milisecond:
DatetimeIndex(['2009-08-08 08:28:25.100000', '2009-08-08 08:28:25.200000',
               '2009-08-08 08:28:25.300000', '2009-08-08 08:28:25.400000',
               '2009-08-08 08:28:25.500000'],
              dtype='datetime64[ns]', freq=None)
