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 heavy?

RKIK is a Rust-based CLI tool designed for stateless and passive NTP inspection, just as dig or ping are for DNS and ICMP.

Link to Documentation page

• Query any NTP server (IPv4 or IPv6)
• Compare offsets between X servers
• Output formats: human-readable or JSON
• Verbose mode for advanced metadata
• Accepts both FQDN and raw IP addresses
• Argument parsing via clap with fallback positional support
