Add this to have something to track this with. The main blocker I see for this is that it's not possible to control location/timezone for dates without that information. ```go package main import ( "fmt" "log" v2 "gopkg.in/yaml.v2" v3 "gopkg.in/yaml.v3" ) var data = ` d: 2021-07-15 ` func main() { mv2 := make(map[string]interface{}) err := v2.Unmarshal([]byte(data), &mv2) if err != nil { log.Fatalf("error: %v", err) } fmt.Printf("--- mv2: %T %v \n", mv2["d"], mv2["d"]) mv3 := make(map[string]interface{}) err = v3.Unmarshal([]byte(data), &mv3) if err != nil { log.Fatalf("error: %v", err) } fmt.Printf("--- mv3: %T %v \n", mv3["d"], mv3["d"]) } ``` Prints: ```bash --- mv2: string 2021-07-15 --- mv3: time.Time 2021-07-15 00:00:00 +0000 UTC ``` Note that `v2` isn't perfect, either, but that at least allows us to handle known dates (e.g. the front matter dates).
