Why the date matters for time-zone conversion
Time-zone offsets are not always constant throughout the year. Some locations represented by Europe/London observe seasonal clock changes, while others keep the same offset. Using the actual date prevents a fixed-offset assumption from producing the wrong local time.

How this time-zone converter works
