Questions
When can London, New York and Singapore meet?
There is no hour inside 09:00–18:00 for everyone. The least awkward hour right now is 11:00 AM–12:00 PM in London = 7:00 AM–8:00 AM in New York = 7:00 PM–8:00 PM in Singapore. For a three-way call, the evening in Singapore and the early morning in New York; otherwise split it into London–Singapore and London–New York.
