I am using dynamic type to access KotlinJS Date javascript functions like getTimezoneOffset. The method return value is dynamic type. How to convert that to Long for example in efficient manner? dynamicDate.getTimezoneOffset().toString().toLong() is not optimal maybe?

1. x.unsafeCast<Y>()
2. val r: Y = x

@konsoletyper Neither of these will return a correct Long!

@tlaukkan However since timezoneoffset is a small number, and it fits in Int, you can use the proposed approach to get Int from dynamic, if that dynamic is really a number.
