如何在数毫秒至数月的时间内将utc集群

Question

Every document in Mongo has timestamp in milliseconds and I get array of documents as result of query. How to cluster data to array of arrays where inner array are documents which belongs to same month ? ( Have to to do this also for weeks, week starts at Monday and the last day is Sunday).

Answer 1

You can get the month and weekday with the time package:

package main

import "fmt"
import "time"

func main() {
    ms := int64(0)
    t := time.Unix(0, ms*int64(time.Millisecond))
    fmt.Println(t.Month(), t.Weekday())
}
