===== Understanding closures with an end date circa 1970 =====
You may occasionally see an RTC in WME with an end date
set as 1970 -01-01 00:00 ±1 day.
*These may not be actively affecting routing in Livemap or the Waze app.
*They may be submitted by any rank user, even if the user is below the rank to have [[#closure feature permissions|RTC permission]].
''These are [[#Report closure feature in the Waze app|Closures reported from within the Waze app]]'''.
A Closure reported from the Waze app does not include an end date in it. These closures are therefore reported to WME with no assigned end date
. The end date field is essentially blank - it is "null". In the [http://en.wikipedia.org/wiki/Unix Unix operating systems] a time is encoded as the number of seconds passed since January 1st, 1970. A "null" date will be zero seconds passed and show a date time of 1970-01-01T00:00 UTC. Adjusted for time zones, and you could have a date-time anywhere from 1969-12-31T12:00, to 1970-01-01T12:00.
This explains the anomalies listed above;
* There needs to be multiple reports to activate them.
* It is possible to have more than one report on the same segment.
These closures are editable by editors in WME who have permission to use the RTC feature. If you do edit and/or delete one of these app-reported RTCs the effects are seen immediately. If you change the end date, the RTC will start affecting traffic like any regular RTC immediately.
