Why Does MySQL Lack Millisecond Precision in TIMESTAMP, and How Has This Been Resolved?

Why Lack of Millisecond Precision in MySQL?

Recent discoveries have brought forth a perplexing issue within MySQL's TIMESTAMP field, revealing its inability to cater to precision beyond second-level accuracy. This poses a significant challenge for PHP and Doctrine users seeking microsecond precision for their TimestampAddable entities.

Concerned developers have pondered potential workarounds, considering alternatives such as BIGINT fields or UDF extensions. However, neither option seems fully satisfactory due to limitations in Doctrine's timestamp handling and the potential for compatibility issues with existing date manipulation functions.

Resolution on the Horizon

Thankfully, MySQL has addressed this long-standing limitation in its most recent version, 5.6.4. This update brings support for fractional seconds in TIME, DATETIME, and TIMESTAMP values, with precision reaching up to microseconds. This significant improvement provides developers with the enhanced precision they require for more accurate data handling.
