Do you supporting inbuilt MongoDb Functions in the MongoDb queries?

I get error if I use this ISODate function:

"SaveDateTime": { "$gt": ISODate("2018-01-01T03:06:53.792+0000") }

For Dates, please use the $date operand instead of the Javascript operand. 

Example: "dt" : { "$gte" : { "$date" : "2013-10-01T00:00:00.000Z"}}. 

Or, you can use our date tokens: Example: "dt" : { "$gte" : $c9_thisyear} where the tokens will be passed in at runtime by Knowi.
