Description

Steps to reproduce:

  1. start NFD
  2. change system clock (manually or with NTP client)
  3. execute nfdc status

Expected: "uptime" field reflects the actual duration NFD has been running

Actual: "uptime" field is inaccurate

Root cause: nfdc calculates uptime by subtracting NFD start timestamp from current timestamp.
Since both timestamps are based on system clock, changing the system clock results in inaccurate uptime.
