Says Esky on the box. Change the date and time before each use by editing the "TAG.txt" text file with any text editor. The file is a simple text file with the date/time stamp in it only. Simply change to today's date and current time (add a few seconds head start to get going) then save the modified file to replace the original. That's it. The file is located on the SD card (memory card you inserted into camera) in the root directory (that means the first folder that opens when you click on the memory card (or SD if you inserted it directly into your tablet, phone or computer) or when you open the drive when the entire camera with card is connected to a computer). Grant you that the instructions for this $6 device stink, but it explains exactly what I just did.
