+      Most systems rely on a daemon (like chronyd or ntpd) to
+      synchronize time. But what if you just want to inspect the
+      current offset between your system clock and one or more NTP
+      servers — without root, without sync, and without installing
+      anything heavyweight?
+
+      RKIK is a Rust-based CLI tool designed for stateless and passive
+      NTP inspection, just as dig or ping are for DNS and ICMP.
