What are the potential pitfalls of storing time values as strings in a database, and how can these be mitigated for accurate calculations?

Storing time values as strings in a database can lead to issues when performing calculations or sorting based on these values. To mitigate this, it is recommended to store time values in a standardized format such as Unix timestamps or database-specific time data types. This allows for accurate calculations and comparisons without the need for additional parsing or formatting.

// Storing time values as Unix timestamps in the database
$timestamp = time(); // Get current Unix timestamp
$query = "INSERT INTO table_name (timestamp_column) VALUES ($timestamp)";
// Perform calculations or comparisons using Unix timestamps
