Convert Async_kernel.Time.now () to GMT

I am using async_kernel as base library. Is there a way to convert Async_kernel.Time.now() value to “GMT”?

A Time.t itself doesn’t have a zone. But if you want a string representing a time in a specific zone, you can use Time.to_string_abs. Or you can use to_date_ofday to get a more typeful interpretation of the time in a specific zone.
