Synchronizing your computer time is important because some exchanges won't accept API calls if your clock is incorrect. Below is a guide to sync your computer time on Windows.
Step 1: Navigate to Control Panel [1]
For Windows 10 | In the search box on the taskbar, type control panel, and then select Control Panel. |
For Windows 8.1 / Windows RT 8.1 | Swipe in from the right edge of the screen, tap Search (or if you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then click Search), enter Control Panel in the search box, and then tap or click Control Panel. |
For Windows 7 | Click the Start button, and then click Control Panel. |
Step 2: In the Control Panel search box (or scroll) to find "Date & Time" and click on it.
Note: It may be under "Clock, Language, and Region" (if you scroll) > Date and Time.
Step 3: Click on the "Internet Time" tab and click "Change Settings"
Step 4: Check the box that says "Synchronize with an internet time server"
Note: time.windows.com or time.nist.gov or pool.ntp.org should be okay servers to sync to
Step 5: Click "Update Now" to immediately sync.
Step 6: Click "Ok"
