Create phone call with Mockaroo for Neo4j I'm following this guide to create a dataset with a call log.
But i don't understand the datatype used for the Date fields and the condition for Start_Date, End_Date and Duration to have coerent values (for example date_start = 10/10/10:1050 date_end=10/10/10:10.55 DURATION = 5)
In that guide, START_DATE and END_DATE are expressed in UNIX epoch time, which is the number of seconds that have elapsed since the beginning of 1970 (in the UTC time zone).

By the way, you will get much better support for neo4j questions at stackoverflow.com.
