NodeJS MySQL Timezone Discrepancy

When fetching data directly from a MySQL database, the returned date is displayed in UTC, assuming the MySQL server is set to UTC. However, upon integrating MySQL with NodeJS, the data is retrieved in the local timezone, UTC 2 in this case. Understanding this discrepancy is crucial for maintaining synchronization between database and application time handling.

The underlying reason for this difference lies in the timezone handling mechanisms of MySQL and NodeJS. MySQL employs the system timezone for date and timestamp operations by default. In contrast, NodeJS uses the operating system's timezone settings unless explicitly overridden. This distinction leads to the deviation when querying MySQL with NodeJS.

To rectify this issue and align NodeJS with MySQL's UTC timezone, the connection configuration in NodeJS must be adjusted. Specifically, the "timezone" property needs to be specified. This parameter ensures that NodeJS maintains the same timezone as MySQL, regardless of the operating system's settings.

In the provided code snippet, the "timezone" property has been added to the MySQL connection configuration:

var db_config = {
  host: 'localhost',
  user: 'xxx',
  password: '',
  database: 'xxx',
  timezone: 'utc'  //<p>By incorporating this property, NodeJS is now configured to retrieve data in UTC, matching the behavior of MySQL. This adjustment eliminates the timezone discrepancy, ensuring consistent handling of timestamps between the database and the NodeJS application.</p>

MySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AM

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

MySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
