Kanthi Subramanian commented on CASSANDRA-17029:
------------------------------------------------
[~blerer] Actually nvm the comment above, the rebase only fixes the first
timestamp test, I was able to reproduce the ambiguous function in the
validations test, trying to fix it.
org.apache.cassandra.exceptions.InvalidRequestException: Ambiguous call to
function maxtimeuuid (can be matched by following signatures:
system.maxtimeuuid : (timestamp) -> timeuuid, system.maxtimeuuid : (bigint) ->
timeuuid): use type casts to

> Add unix time conversion functions
> ----------------------------------
>
> Key: CASSANDRA-17029
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17029
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL/Syntax
> Reporter: Benjamin Lerer
> Assignee: Kanthi Subramanian
> Priority: Normal
>
> It will be useful to have some functions to conver unix time values into C*
> native types, like:
> * {{toDate(bigint)}}
> * {{toTimestamp(bigint)}}
> * {{mintimeuuid(bigint)}}
> * {{maxtimeuuid(bigint)}}
> +Additional info for newcomers:+
> Those new functions need to be added to
> {{org.apache.cassandra.cql3.functions.TimeFcts}} and some unit tests need to
> be added to {{org.apache.cassandra.cql3.functions..TimeFctsTest}}. The other
> functions in {{TimeFcts}} provide some good example of how to create new
> functions.
> As it is a new functionality they need to be mentioned in the {{NEWS.txt}}
> file.
