+name: ntp-time
+description: Query the current date and time from an NTP server with a bundled script. Use when a user asks for network time, wants to compare system time with NTP time, or needs a minimal example skill that includes a script and a reference file.
+---
+
+# NTP Time
+
+Use `scripts/get-ntp-time.ts` instead of reimplementing the NTP request.
+
+Default to `pool.ntp.org` unless the user names a different server.
+
+Run:
+
+```bash
+tsx scripts/get-ntp-time.ts
+tsx scripts/get-ntp-time.ts time.google.com
+node --experimental-strip-types scripts/get-ntp-time.ts
+```
+
+Return the server used, the UTC ISO timestamp, and the Unix epoch.
+
+Read `references/ntp.md` only if you need protocol details or need to explain the output.
+
+If the request fails, report the network error clearly and do not guess the time.

+# NTP Notes
+
+- NTP uses UDP port `123`.
+- A minimal client can send a 48-byte packet with the first byte set to `0x1b`.
+- The server transmit timestamp is stored in the last 8 bytes of the response.
+- NTP timestamps count seconds since `1900-01-01T00:00:00Z`.
+- Unix timestamps count seconds since `1970-01-01T00:00:00Z`.
+- Convert NTP seconds to Unix seconds by subtracting `2208988800`.
+
+The bundled script prints:
+
+- `server`: hostname queried
+- `utc_iso`: UTC timestamp in ISO 8601 form
+- `unix_epoch`: Unix time as a floating-point number
+
+Typical usage:
+
+```bash
+tsx scripts/get-ntp-time.ts
+node --experimental-strip-types scripts/get-ntp-time.ts pool.ntp.org --timeout 2.0
+```
