There is a C++ standard function called time() but it only has second
resolution.

This is not correct. From the C draft standard:

7.23.2.4 The time function

Description

[#2] The time function determines the current calendar time.
The encoding of the value is unspecified.

Returns

[#3] The time function returns the implementation's best
approximation to the current calendar time. The value
(time_t)-1 is returned if the calendar time is not
available. If timer is not a null pointer, the return value
is also assigned to the object it points to.

If you want to keep it standard:

Look up "clock()", the best resolution the standard can give you is
1/CLK_TCK second

I suppose that depends on which standard you follow.
CLK_TCK is (if memory serves) in the POSIX standard, but
the C and C++ standards call it CLOCKS_PER_SEC.
