To convert a UTC (Coordinated Universal Time) timestamp to a TAI (International Atomic Time) timestamp in Python, you can use the pytai package. Here's an example of how to install and use the pytai package for this conversion:

Install the pytai package using pip. You can do this by running the following command in your terminal or command

pip install pytai

Import the pytai package in your Python script:

import pytai

To convert a UTC timestamp to a TAI timestamp, you can use the pytai.TAI.from_utc() method. This method takes a UTC timestamp as a datetime.datetime object and returns a TAI timestamp as a pytai.TAI object. For example, to convert a UTC timestamp of "2023-03-21 12:00:00" to TAI, use the following code:

import datetime
import pytai

# Create a datetime object for the UTC timestamp
utc_timestamp = datetime.datetime(2023, 3, 21, 12, 0, 0)

# Convert the UTC timestamp to TAI
tai_timestamp = pytai.TAI.from_utc(utc_timestamp)

# Print the TAI timestamp
print(tai_timestamp)

This will output the TAI timestamp as a pytai.TAI object, which you can manipulate as needed.
