Rethinkdb query to fetch data between 2 epoch times

I'm trying to run a ReQL query to fetch the data between 2 epoch times, i have a field called "lastUpdatedDttm" using which i'm trying to run the query like below. The lastUpdatedDttm field type is "number" and is just new date().getTime()

r.db('my_db').table('my_table').getAll('/mypath', { 
index: 'path' }) .filter(r.row('updatedBy').eq('id').and(r.row('lastUpdatedDttm').during(1512864000000, 1513209600000)))

The above query returns error, e: Not a TIME pseudotype:

Am i missing something in the query?

i believe duration needs time objects as arguments so you need to use the epochTime method to convert your times, so

r.db('my_db').table('my_table').getAll('/mypath', { index: 'path' })
  .filter(
    r.row('updatedBy').eq(id)
      .and(
        r.row('lastUpdatedDttm')
          .during(
            r.epochTime(1512864000000 / 1000),
            r.epochTime(1513209600000 / 1000)
          )
      )
    )

you should also make sure lastUpdatedDttm is stored as a date

if you are storing lastUpdatedDttm as a number generated by new Date().getTime() you can do

r.db('my_db').table('my_table').getAll('/mypath', { index: 'path' })
  .filter(record => {
    return record('updatedBy').eq(id).and(
      r.epochTime(record('lastUpdatedDttm').div(1000))
        .during(
          r.epochTime(1512864000000 / 1000),
          r.epochTime(1513209600000 / 1000)
        )
    )
})
