Projekt je bil ustvarjen kot forku standardne implementacije protokola NTPv4 (NTP Classic 4.3.34), osredoto\u010den na prenovo izvorne kode s ciljem pove\u010danja varnosti. Izvorna koda NTPsec se distribuira pod licencami BSD, MIT in NTP.    <\/p>\n<p>NTPsec se razvija pod vodstvom Erica Raymonda (Eric S.
