What time is it in Singapore when it is noon in London?
The converter above answers that for whichever date you pick — and the date matters, because the gap is not constant through the year.

Convert a time from London to Singapore on any date. London changes its clocks for daylight saving and Singapore does not, so the difference between them shifts by an hour twice a year.

London and Singapore
London runs on Europe/London and Singapore on Asia/Singapore. London changes its clocks for daylight saving and Singapore does not, so the difference between them shifts by an hour twice a year.
This is why the converter above asks for a date. A meeting arranged in October for a date in November can land an hour off if you assume today's difference still holds — the clocks move between the two moments, and only one side may move.
The safest habit for scheduling across zones is to agree on the local time in one place and let each side convert, rather than agreeing on "the difference". The difference is a property of a date, not of a pair of cities.
