Parsing a datetime using Cypher

Cypher’s datetime() function also accepts STRING values formatted to the ISO8601 standard.

The time parameter is a date string in the ISO8601 standard format

The following examples convert a date string in ISO 8601 format to epoch millis using both APOC and Cypher:

apoc.date.fromISO8601

RETURN apoc.date.fromISO8601('2020-11-04T12:21:33.000Z') AS outputInMs;

Using Cypher’s datetime() function

RETURN datetime('2020-11-04T12:21:33.000Z').epochMillis AS outputInMs;
