From Wikipedia, the free encyclopedia
| Windows Software | Price | Time Signals | Notes |
|---|---|---|---|
| NMEATime2[1] | $20.48 |
|
The PC clock is disciplined to the NMEA string from the GPS with a control loop that uses the same techniques in disciplining OCXO oscillators and atomic Rubidium clocks. |
| NetTime[2] | free |
|
Only one I've tested with a clean UX that defaults to NTP Pool addresses. |
| BktTimeSync by IZ2BKT[3] | free |
|
Needs more extensive testing, including with USB GPS. |
| winacts-32-bit.exe[4] | free |
|
Needs testing with modem on my laptop. |
| Meinberg NTP[5] | free |
|
Better than Windows' built-in NTP client because Windows only updates its clock once a week or so. Meinberg NTP alters the clock rate, as well as initially setting the clock time, so that the clock will stay as close as possible to UTC between corrections. It is supposedly the official Network Time Protocol client software.[6] No graphical UX, and is thus confusing to install, configure, and use. |
| Use only as backup time sources | |||
| ToyNTP[7] | free |
|
Syncs time to either NTP servers or a local GPS. Designed to work with the Garmin GPS 18x LVC, which provides a 1PPS signal.
NTP portion required UDP port 123 to be open. |
| F6CTE's CLOCK[8] | $40 |
|
Supports the widest variety of time signals, including GPS, radio, and Internet, but not the most accurate.
Need to test if this can link to SDRsharp. |
| ClockWatch Pro for Windows[9] | $30 |
|
Only Windows software that supports NIST's ACTS modem time service. |
| nistime-32bit.exe[10] | free |
