How to modify DateTime value

[jorcadet009]

// Fumb.PlayerStats.PlayerStatStartDate
// Token: 0x0600E45B RID: 58459 RVA: 0x000419E8 File Offset: 0x0003FBE8
[Token(Token = "0x600E45B")]
[Address(RVA = "0x1BEFC8", Offset = "0x1BEFC8", VA = "0x1BEFC8")]
public static DateTime get_DateStart()
{
	return default(DateTime);
}

this is the function I wanna hook

import "frida-il2cpp-bridge";

Il2Cpp.perform(() => {
  console.log("Unity version: ", Il2Cpp.unityVersion);
  let unityframework = Il2Cpp.domain.assembly("Assembly-CSharp");
  let PlayerStatStartDate = unityframework.image.class(
    "Fumb.PlayerStats.PlayerStatStartDate"
  );
  let get_DateStart = PlayerStatStartDate.method("get_DateStart");

  get_DateStart.implementation = function () {
    console.log("get_DateStart called");
    let date = this.method<Il2Cpp.DateTime>("get_DateStart").invoke();
    console.log("DateStart: ", date.toString());
    return null;
  };
});

and this is my code to get the value that the function will return
get_DateStart called DateStart: 2/28/2025 6:51:05 AM
and this is the log, I tried many times but it always return wrong formart
