What Z means in MongoDB Date format

Question

I am using mongodb and I noticed ISODate("2016-11-07T20:22:48.743Z"). This date format is in one of the newly created collection's field-value. I don't know what "743Z" means since in the remaining raws, all are saved with "0Z".

Please help me understand the meaning.

Answer 1

Z in time formats refers to Zulu time, also known as UTC, and is therefore a timezone indicator.
