i have changed the source code at utils/GsonDate and it solved this problem
i do not make sure if it is the best soultion but it solved my problem.

    public Date deserialize(JsonElement jsonElement, Type type,
                            JsonDeserializationContext jsonDeserializationContext) throws JsonParseException {
        SimpleDateFormat formatter = new SimpleDateFormat(FORMAT);
        try {
            return formatter.parse(jsonElement.getAsString());
        } catch(ParseException ex1) {
            // Check if maybe it's in the old format
            Bukkit.getLogger().log(Level.WARNING, "Could not parse date in new format, trying old format");
            try {
                SimpleDateFormat oldFormatter = new SimpleDateFormat("MMM d, yyyy, H:mm:ss a");
                return oldFormatter.parse(jsonElement.getAsString());
            } catch(ParseException ex2) {
                Bukkit.getLogger().log(Level.WARNING, "Could not parse date in new format, trying old format");
                try {
                    SimpleDateFormat oldFormatter = new SimpleDateFormat("MMM d, yyyy, hh:mm:ss a", Locale.ENGLISH);
                    return oldFormatter.parse(jsonElement.getAsString());
                } catch(ParseException ex3) {
                    try {
                        SimpleDateFormat oldFormatter = new SimpleDateFormat("MMM d, yyyy, HH:mm:ss");
                        return oldFormatter.parse(jsonElement.getAsString());
                    } catch(ParseException ex4) {
                        throw new JsonParseException(ex4);
                    }
                }
            }

Thanks for submitting your issue. This is indeed a long standing issue where users have old date formats. A few are covered already but looks like some are still missing.
