Description
Sets the datetime value for a key. If the key does not exist, then create the key and set its value. If the key already exists, then overwrite the value of this key. If more than one key with the same name already exists, then overwrite the value of the first key. Notice that the IgnoreCase property (true by default) determines whether the key name will be matched in a case-sensitive manner.

Examples
This example sets the value of the birthday key and the createdate key in the JSON string.
// Integer SetValueDateTime (string Key, datetime Value)
DateTime ldt_CreateDate,ldt_Birthday
JsonPackage ljpk_User
ljpk_User = Create JsonPackage
// Loads the JSON string to the JSONPackage object
ljpk_User.loadstring( '{"id":100,"name":"Henry.Ken","birthday":"1998-12-01 08:02:30","CreateDate":1543900359 }')
ljpk_User.SetValueDateTime("birthday", DateTime(Today(), Now()))
// This will change the ItemType of the CreateDate key to JsonStringItem!
ljpk_User.SetValueDateTime("CreateDate", DateTime(Today(), Now()))
// GetValueDateTime can also get a long value or a string value.
// It is recommended to check if it is a datetime value, otherwise exception may be thrown.
ldt_CreateDate = ljpk_User.GetValueDateTime("CreateDate")
ldt_Birthday = ljpk_User.GetValueDateTime("birthday")
