Description

when I declare a struct
type Test struct { Start time.Time form:"start"}
I can send a request /test?start=2023-09-02T15:00:00Z. But, When I define a custom time type, like this:
`
type Time struct {
time.Time
}

type Test struct {
Start Time form:"start"
}
`
When I send a request, I get error "invalid character '-' after top-level value".

How to reproduce

package main

import (
	"fmt"
	"net/http"
	"time"

	"github.com/gin-gonic/gin"
)

type Time struct {
	time.Time
}

type Test struct {
	Start Time   `form:"start"`
}

func main() {
	engine := gin.Default()
	engine.GET("/test", func(c *gin.Context) {
		var test Test

		/*******/
		query := c.Request.URL.Query()
		fmt.Println(query)
		if err := c.ShouldBindQuery(&test); err != nil {
			c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})
			return
		}

		fmt.Println(test)
	})

	engine.Run(":8080")
}

Expectations

$ curl http://localhost:8080/test?start=2023-09-02T15:00:00Z

Actual result

$ curl -i http://localhost:8080/test?start=2023-09-02T15:00:00Z
{
    "error": "invalid character '-' after top-level value"
}

Environment

• go version: go 1.23.0
• gin version (or commit ref): 1.10.0
• operating system: linux

Thanks, but I don't want to add "" in request. because time.Time can do it without "". In source code, I found error in setWithProperType case reflect.Struct, when value is time.Time, the function will call setTimeField, but other type will call json.Unmarshal. I am finding a way to solve it, maybe there a way that entering case rteflect.Ptr can solve it(I guess)
