In general, nginx can provide time with millisecond resolution.
For example, see the $msec variable (http://nginx.org/r/$msec).

Note though that precision is not the same thing as resolution.
Since nginx updates time only at the start of an event loop
iteration, and various operations, such as disk access, might take
significant time, likely precision will be worse than 1
millisecond. Further, precision might be much worse if you've
configured nginx to update time only once in a while by using the
timer_resolution directive (http://nginx.org/r/timer_resolution).

Hope this helps.
