STEPS IN TIME SYNCHRONIZATION USING PAGASA NTP SERVER FOR WINDOWS XP
Step 1: Left double-click on the time (bottom-right of your desktop)
Step 2: From the Menu that opens choose Adjust Date/Time. The Date/Time Properties Dialog Box is displayed
Step 3: Left click the "Internet Time" tab
Step 4: Type "ntp.pagasa.dost.gov.ph" in the server textbox. Left click the "Update Now" button
Step 5: Wait for a few seconds
Step 6: Left click the "OK" button
NOTE: If you notice that after synching, your computer clock didnít match the PhST, just keep on refreshing until it finally synched with PhST. It is normal at the beginning, because it will take time to load a page. Refresh it at least three times (3x) until it displayed the correct PhST.
