time-changer

GUI tool written in Go (Fyne) to change the Windows system time from the desktop.

Note: Must be run as Administrator — Windows requires elevated privileges to set the system clock.

Quick start

go build -o time-changer.exe .
# Right-click → Run as Administrator:
time-changer.exe

Usage

The app presents a calendar and time picker. Select the target date and time, then confirm to apply it as the new system time.

Supported date selection: year/month/day via calendar widget; hours, minutes, seconds via dropdowns.
