I'm trying to insert 0 as a time-stamp value but it returns error Invalid Timestamp.

Ok, I'm having trouble reproducing this. Which version are you working against?

Raghu-Gurrala commented 8 years ago

I’m using version 2.2.0

Thanks Raghu

$ echo "put metric.test 0 0 tag=value" | nc localhost 4242 put: illegal argument: invalid timestamp: 0

The change to make a timestamp of 0 work will require a lot of retooling both on the insert and the query side. Mostly for the query side. A timestamp of 0 is easily equated with FALSE in a few cases. Out of curiosity, what use case do you need to use the timestamp Thu, 01 Jan 1970 00:00:00 GMT

Hi Jonathan,

Apologies for late reply, There is no specific use case, I was testing out throughput using false data and purposely changed the timestamp to 0.

Thanks, Raghu
