Helpful extras you might miss at first glance

Custom time format

Click the "12 Hour / 24 Hour" button to switch how the time displays. It's perfect if you prefer Reading times without AM/PM or want the classic 24-hour clock style.

Show seconds and UTC offsets

You can toggle whether to include seconds and the UTC offset. This is great for precision work or scheduling where exact seconds or time difference labels matter.

Daylight Saving checkbox — built for clarity

The "Daylight Saving Aware" checkbox is included, even though GMT and WIB never observe DST. It's there in case future zones are added. For now, you can leave it off.

What if I want to know Jakarta time for an event in London?

Let’s say you're planning an online summit from the UK and you want your Indonesian attendees to catch the keynote live. Input your London time under GMT, and you’ll instantly see what that is in WIB. For example, if your keynote starts at 10 AM GMT, attendees in Jakarta will see 5 PM WIB on the tool.
