The reliable and budget priced Clock77 radio clock supplies the atomclock exact time over the PCI bus. A switching from and to summer time is not nescessary. The accuracy of the radio clock's time is +/- 50 ms. Windows 7 / Vista / XP / 2000 / 2003 / 2008 / 2008 R2 / 95 / 98 / ME / NT 4.x drivers (server and workstation) are available. For Windows 7 / Vista / XP / 2000 / 2003 / 2008 / 2008 R2 / NT 4.x the Clock77 software is executed as "NT service". Therefore, the time will be updated even when no user is logged in.

We added a graphical monitor program which allows to check the positioning and the quality of the received signal. This is nescessery for adjusting the clock in distorted or large distance locations. The clock incorporates a highly intelligent algorithm for the dectection of faulty times and the correction of them.

You can distribute the received time easily to other clients in the network. The manual describes how to do this. The new enhanced antenna now gives a larger covered area and has a built in LED for function control. The QUANCOM drivers need very little processing time and save processor resources. You will not detect any essential system impact.
