Description:
------------
According to current documentation, date('u') returns "Milliseconds (added in PHP 5.2.2) | Example: 54321".

I suspect that what is meant is microseconds (10^-6 s), not milliseconds (10^-3 s). Otherwise, the example value doesn't make sense.

Reproduce code:
---------------
shell> php -r 'echo date("u")."\n".date("u")."\n";'


Expected result:
----------------
microseconds, not milliseconds

Actual result:
--------------
microseconds (apparently)

The source (below)

case 'u': length = date_spprintf(&buffer, 32 TSRMLS_CC, "%06d", (int) floor(t->f * 1000000)); break;

Which is 10^-6 - microseconds.

I don't have a CVS account but here's a small docbook patch for it:

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
