enables high-resolution timestamps,
currently used for request start time

This is automatically enabled if mod_accesslog log record format uses
high-resolution format specifiers in the template, but this feature
needs to be enabled if that is not the case and a high-resolution
request start time is desired for use in lua scripts run by mod_magnet,
e.g. to measure time-to-first-byte
