n.b.: I changed this to pass-by-value rather than by-reference based on this
comment in time.h:

// All time classes are copyable, assignable, and occupy 64-bits per
// instance. Thus, they can be efficiently passed by-value (as opposed to
// by-reference).

If you revisit startup_metric_utils, I propose that you change it from by-ref to
by-value.
