Current Date in JSON Format
The current timestamp formatted the way JavaScript's Date.toJSON() and most REST APIs represent dates — ISO 8601 with milliseconds and a UTC marker.

Why APIs Use This Format
This format — YYYY-MM-DDTHH:mm:ss.sssZ — is what JavaScript's Date.prototype.toJSON() and JSON.stringify() automatically produce for date objects. It's also the format most REST APIs return and expect for timestamps, since it's precise to the millisecond and unambiguous across timezones thanks to the trailing "Z" (Zulu time / UTC marker).
Frequently Asked Questions
It's an ISO 8601 timestamp with millisecond precision and a 'Z' suffix marking UTC, exactly as produced by JavaScript's Date.toJSON() method.
The 'Z' stands for 'Zulu time,' the military and aviation term for UTC, and signals that the timestamp has no local timezone offset applied.
