Why people usually need a time conversion, and which tool answers it.

You’re setting a call between New York, London and Colombo.
Daylight saving changes on different dates in different countries. The risk: someone joins at 3 am, or misses the call entirely.
What you need
The meeting time in every city, for that date.
Time Zone Converter
Your timesheet wants decimal hours, and you worked 1 hour 45 minutes.
Minutes aren’t hundredths of an hour. The risk: being underpaid, or overbilling a client.
What you need
The exact decimal hours (1.75) or minutes.
Hours to Minutes
A log line, token or API response gives a time like 1790000000.
Epoch seconds and milliseconds are unreadable. The risk: misreading when something happened, or when it expires.
What you need
A readable date and time, in any zone.
