17. Unix/Epoch Time Conversion

Write a Pandas program to convert unix/epoch time to a regular time stamp in UTC. Also convert the said timestamp in to a given time zone.

Sample Solution:

Python Code :

import pandas as pd
epoch_t = 1621132355
time_stamp = pd.to_datetime(epoch_t, unit='s')
# UTC (Coordinated Universal Time) is one of the well-known names of UTC+0 time zone which is 0h.
# By default, time series objects of pandas do not have an assigned time zone.
print("Regular time stamp in UTC:")
print(time_stamp)
print("\nConvert the said timestamp in to US/Pacific:")
print(time_stamp.tz_localize('UTC').tz_convert('US/Pacific'))
print("\nConvert the said timestamp in to Europe/Berlin:")
print(time_stamp.tz_localize('UTC').tz_convert('Europe/Berlin'))

Sample Output:

Regular time stamp in UTC:
2021-05-16 02:32:35

Convert the said timestamp in to US/Pacific:
2021-05-15 19:32:35-07:00

Convert the said timestamp in to Europe/Berlin:
2021-05-16 04:32:35+02:00
