Pine script 下拉式时间更改

大家晚上好

我试图编写一个下拉列表，当选择不同的下拉列表时，会更改输入时间

因此，例如，如果选择UTC+1，它将更新输入的绘图信息

我已经开始为UTC 0、UTC+1和UTC+2编写以下代码，但在第30行（用整数声明）上出现错误

这可能吗。谢谢你抽出时间

DD0 = "UTC 0", DD1 = "UTC + 1", DD2 = "UTC + 2"

var string  DropDownInput   = input(title="Select Input", defval=DD0, options=[DD0, DD1, DD2])

上述情况是否可能？
