Exploring Timestamp Conversion to Regular Date in SQLite

In the world of databases, particularly Android databases using SQLite, handling timestamps is a frequent task. Many times we come across large integer numbers like "851558400000" and need to convert them into readable dates. Let's dive into how to accomplish this conversion and understand the format of these timestamps.

Understanding the Timestamp Format

The timestamp "851558400000" is a type of Unix timestamp, also known as an epoch time. This format represents the number of milliseconds that have elapsed since the Unix epoch, which is January 1, 1970, 00:00:00 UTC. It is a standard format used in many applications, especially Android, for storing time values.

Converting Timestamps in SQLite

SQLite provides several built-in date and time functions that allow you to manipulate and convert timestamps easily. To convert a timestamp like "851558400000" to a regular date, you can use the following SQL query:

Explanation

Here's a breakdown of the query:

851558400000 / 1000: This division converts milliseconds to seconds because Unix epoch timestamps typically use seconds.

'unixepoch': This modifier tells SQLite to interpret the number as a Unix timestamp.

The function datetime will output the converted timestamp in the "YYYY-MM-DD HH:MM:SS" format, providing a human-readable date and time.

Practical Example

Here’s how you might query an Android SQLite database to convert a stored timestamp:

This query will transform the values in your_timestamp_column from Unix timestamps to regular dates and name the output column readable_date.

Conclusion

Dealing with timestamps, especially in SQLite databases used in Android applications, becomes effortless once you understand how to convert them. The timestamp "851558400000" represents a specific point in time, and using SQLite's built-in functions, you can quickly convert it to a readable date format.

By mastering this technique, you enhance your ability to interact with and analyze your data, ensuring that you can always derive meaningful information from your timestamps.
