What you can do here

Useful outcomes you get right away:

• Turn a huge uptime or benchmark value into days, hours, and minutes you can read
• Toggle seconds or milliseconds so the number matches your log line
• Copy a friendly breakdown straight into postmortems or customer updates

Readable ranges for ops and support

Full view uses fixed-length year and month chunks so multi-day spans become scannable; switch to the hours-focused layout when you only care about the tail of the duration.
