inlinestatic

Convert Timestamp to RFC 3339 date string format. The output will always be Z-normalized and uses 3, 6 or 9 fractional digits as required to represent the exact value. Note that Timestamp can only represent time from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. See https://www.ietf.org/rfc/rfc3339.txt

Example of generated format: "1972-01-01T10:00:20.021Z"

Returns
The string representation of the given timestamp.
Exceptions
IllegalArgumentExceptionif the given timestamp is not in the valid range.
Deprecated:
Use Timestamps#toString instead.
