TimeTools Freeware NTP Server Utility Software For Windows

This software utility is a freely downloadable Freeware application. It allows any Windows NT4/2000/XP/Vista PC to synchronize with an Internet or locally based time reference using the Network Time Protocol. The utility can also act as a reference for other network time clients.

The Network Time Protocol is a standard protocol for distributing accurate time around a computer network. It operates on a hierarchical basis. The most accurate servers reside at the highest levels or stratums of the heirachy. Each level obtains time from the level above. In this manner time can be distributed to thousands of clients without swamping a single reference.

There are a number of accurate time references available across the internet, many are maintained by government standards departments or universities. Most are freely accessible without any subscription fee.

The utility contains a list of the most popular time servers that reside on the internet. Any number of servers can be specified, which the utility will poll at specified intervals. The status of each server will be displayed along with reference details, round trip delays and time offset from the PC's system time.

The PC's system and local times are displayed prominently by the application. Also displayed is the time of the last poll, synchronization reference and last adjustment if system time updates are selected.

If required, the utility will update and maintain the PC's system time. This is a selectable option. NTP will only be served to clients if time updates are specified. The server with the lowest stratum and lowest round-trip delay will be selected for synchronization of the system time.

Options Window Features

Adjust System Time - Allows the PC's system time to adjusted and maintained by the utility.

Highlight Reference Time Greater Than - Highlights any servers which have themselves not synchronized with an external reference for greater than a specified amount of time. This is useful because it can highlight servers that are having trouble synchronizing with there own hardware reference clocks and may be about to go out of service.

Highlight Stratum Greater Than - Highlights any selected time references with a stratum greater than the specified level. This can be used to highlight servers that have changed stratum due to loss of contact with their primary time reference.

Serve NTP to Clients - This option enables the utility to serve NTP to network time clients for synchronization purposes.

NTP Stratum - Allows the stratum level of NTP responses to network clients to be set or adjusted.

NTP Polling Frequency - Sets how often the utility is to poll the list of specified servers.
