Philippine Time (PH Time)

The clock in a phone or laptop drifts a little every day, and it only corrects itself when it next checks in with a time server — something a lot of devices do rarely, if ever. So instead of just reading your device's own clock, this page asks the server for the time, measures how long that question and its answer took to travel, and works out from that how far off your device's clock actually is.

What you see is your device's clock with that difference removed, and the page states the difference itself, so you know whether the number in the corner of your screen can be trusted. Servers keep their clocks in step with proper time sources as a matter of course, which makes a server a far steadier reference than a device left on its own. Whatever margin remains comes from the network itself — a stable connection gives a tighter number than a congested one.

The page checks several times and keeps the fastest exchanges, then shows the margin that's left beside the result. It checks again every ten minutes while the tab stays open, whenever you come back to it, and the moment it notices your device's clock has been changed.

The Philippines keeps a single time zone nationwide — Philippine Time (PHT), UTC+8 — from Batanes in the north to Tawi-Tawi in the south, with no local variation and no daylight saving adjustment at any point in the year. That's true whether your device happens to be set to Asia/Manila already or to somewhere else entirely.

The big clock at the top of this page always shows your own device's time zone, so if you're already in the Philippines it's showing PHT without you having to do anything. If your device is set to another zone — an OFW checking home, or a phone that auto-set itself while travelling — the Philippines row further down the page always gives PHT on its own, correct and separate from whatever the big clock above happens to show.

One more thing worth saying plainly, since it's the one mix-up this kind of search keeps running into: Philippine Time is never abbreviated "PST" on this page, because that collides with US Pacific Standard Time, a completely different zone many hours away. Write "PHT" or "Philippine Time" instead.

Switch to fullscreen and the time takes over the display with nothing else on it, in digits big enough to read from across a room — on a classroom board, next to a livestream, on a second monitor, or on a tablet left out on a desk. The page keeps correcting itself the whole time it's open, so a clock left running all day stays right, and while it's fullscreen it asks the device to keep the screen on, wherever the browser allows that.

For counting toward a specific time rather than showing the time itself, the pages that count down to common clock times are linked below, and the countdown tool counts to any date you pick. The alarm clock rings at a time you set, and the week number page gives today's week of the year.

Below your own time, the page shows Philippine Time on its own row — since the country keeps just the one zone, there's no list of provinces or regions to pick from, only the single PHT reading — and then the time in major cities around the world, each one marked with how many hours it's ahead of or behind the time shown above. Select any of them and it takes over the big display, fullscreen included, until you switch back to your own.

The clock follows 12-hour or 24-hour format, whichever you pick, and the choice carries over to the other tools too. Next to the date sit today's ISO week number and the day of the year. Seconds can be turned off for a calmer display, and that choice is remembered on this device as well.
