php - Why doesn't MySQL support millisecond / microsecond precision?

Question

So I just found the most frustrating bug ever in MySQL.

Apparently the TIMESTAMP field, and supporting functions do not support any greater precision than seconds!?

So I am using PHP and Doctrine, and I really need those microseconds (I am using the actAs: [Timestampable] property).

I found a that I can use a BIGINT field to store the values. But will doctrine add the milliseconds? I think it just assigns NOW() to the field. I am also worried the date manipulation functions (in SQL) sprinkled through the code will break.

I also saw something about compiling a UDF extension. This is not an acceptable because I or a future maintainer will upgrade and poof, change gone.

Has anyone found a suitable workaround?

For information for the next readers, this bug has finally be corrected in version 5.6.4:

"MySQL now supports fractional seconds for TIME, DATETIME, and TIMESTAMP values, with up to microsecond precision."
