Age Gauge

See Age Gauge for the concept.

To set a specific time as the last success:

from spectator import Registry

registry = Registry()
registry.age_gauge("time.sinceLastSuccess").set(1611081000)

last_success = registry.new_id("time.sinceLastSuccess")
registry.age_gauge_with_id(last_success).set(1611081000)

To set now() as the last success:

from spectator import Registry

registry = Registry()
registry.age_gauge("time.sinceLastSuccess").now()

last_success = registry.new_id("time.sinceLastSuccess")
registry.age_gauge_with_id(last_success).now()
