About the time in Si Mum
Si Mum runs on Asia/Bangkok, which puts the city UTC +7 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
If you are coordinating from another country, the shortcut is the working window: a normal Si Mum day of 09:00–17:00 falls between 02:00–10:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
Around 6,500 people live in Si Mum, and all of them keep the same civil time, so the reading above applies to the whole urban area — not just the city centre.
