is another straightforward, free Windows application that retrieves the current time from NIST servers to adjust the PC clock. It is known for its simplicity and ability to switch to alternative servers if the primary one fails. Like iTimeSync, it's a great, lightweight option for users who want a dedicated NIST sync tool.
