100% reference NTP implementation:
RFC5905, RFC5906, RFC5908, RFC5909
Microsoft platforms incl.:
Microsoft Windows 10/8/7
Microsoft Server 2016/2012/2008

network time protocol for windows 32/64 bit

Microsoft Windows allows you by defaults to synchronize your PC clock via Internet. However, standard built-in Windows SNTP client has serious functional and cyber-security limitations compering to std. reference NTP implementation defined at www.ntp.org.

 

Elproma has prepared a Windows binary (.EXE) compilation of reference NTP. All software is digitally signed to ensure its integrity and originality. It basis C-code of NTP v4.2.8 covering rfc5905, rfc5906, rfc5907, rfc5908, rfc5909 and rfc 4330. It supports both: native NTP Server and Slient operating stratum 0-15, a SNTP version 4. This software offers accuracy x1000 more accurate compering to std. Windows client. It uses slew-down clock adjusting technology synchronizing both frequency & phase of Windows software clock operating at kernel level.
