Converting UNIX Timestamps to Pandas Datetime in Python

Working with time data can often become complicated, especially when dealing with different formats. One common issue faced by data professionals is converting UNIX timestamps to a format that is readable and useful for analyses, such as Pandas datetime. This post will guide you through the process of converting UNIX timestamps with UTC offsets to Pandas datetime objects in Python, ensuring you get it right every time.

The Problem

You might be importing UNIX timestamps from an external source which looks something like this:

After attempting to convert these timestamps into a readable format, you may find that the resulting datetime values are off by several hours. For example:

While your original timestamps indicated two specific times:

The discrepancy occurs due to the UNIX timestamps being interpreted incorrectly because of the UTC offset, denoted by the +1000 in the string.

The Solution

To troubleshoot and effectively convert your UNIX timestamps to the correct datetime format in Pandas, follow this systematic approach:

Step 1: Extract UNIX Time and Offset

You can use regular expressions (regex) to extract the UNIX time and its associated UTC offset from the strings.

Step 2: Convert to Datetime

Now that you have unix and offset in separate columns, convert the UNIX timestamp to a datetime object:

Step 3: Adjust for UTC Offset

If the timestamps are valid (i.e., not NaT), you need to add the UTC offset to ensure the correct local time is displayed:

Conclusion

By following these steps, you will be able to convert UNIX timestamps that include UTC offsets to properly formatted Pandas datetime objects. This approach will ensure that your datetime data is accurate and interpretable, allowing you to proceed with your data analysis without losing time to formatting issues.

With just a few lines of Python code, tackling time-based data becomes a breeze! Happy coding!
