Inconsistent time.Time value when changing interpolateParams

[mcartmell]

Issue description

When reading a time.Time value from a DATETIME column of value 0000-01-01 00:00:00, the year returned is inconsistent when using different values for the interpolateParams parameter.

I would expect the time value to be the same regardless of the interpolateParams setting.

I noticed this issue when upgrading from v1.5.0 to v1.6.0. Could not reproduce on v1.5.0.

Example code

package main

import (
	"database/sql"
	"fmt"
	"time"

	_ "github.com/go-sql-driver/mysql"
)

func main() {
	var results []time.Time
	vals := []bool{false, true}
	for _, val := range vals {
		db, err := sql.Open("mysql", fmt.Sprintf("user:password@/dbname?parseTime=true&interpolateParams=%t", val))
		if err != nil {
			panic(err)
		}

		if _, err := db.Exec("create temporary table `time_params_test` (`id` int, `dt` datetime);"); err != nil {
			panic(err)
		}

		if _, err := db.Exec("insert into `time_params_test` values(1, '0000-01-01 00:00:00');"); err != nil {
			panic(err)
		}

		var res time.Time
		row := db.QueryRow("select dt from `time_params_test` where id = ?;", 1)
		if err := row.Scan(&res); err != nil {
			panic(err)
		}
		results = append(results, res)
	}
	fmt.Printf(`
interpolateParams=false: %v
interpolateParams=true : %v
match=%t`, results[0], results[1], results[0] == results[1])
}

Error log

interpolateParams=false: 0000-01-01 00:00:00 +0000 UTC
interpolateParams=true : 0001-01-01 00:00:00 +0000 UTC
match=false
