Thanks,
I would like to know how are point in time and point of time different and whats their correct usage
I have not used "point of time", and I can't say I recall hearing it. However, based on just a few glances - quick looks and observations that is to say - it appears that, perhaps, "point of time" is used in technical contexts or maybe things technological. For general purposes - general language - I would really recommend just using "point in time".
I did a UK search. It's interesting because it's possible to search specific countries with Google.

Google - Australia
Google - New Zealand - and etcetera
As an aside, I'd like to add this:
I've learned to consult Google even if
I have not heard the expression. In fact, I'm probably going to stop learning new things altogether because everything is recorded in Google. If we want to know something, we should go to Google. :shock: I don't have to know anything. Google has it all taken care of for me. :roll:
Be careful of using "at this point in time". Language critics have singled that one out for special attention. Too wordy they say. Just say "at this time". I kind of have to agree with this, but I wouldn't fault anyone for using it. It's not
that bad.
