Nope. It's from the 1980s. Its display was made of red LEDs. Those use too much energy to run off batteries for a reasonable amount of time. Modern clocks use liquid crystal displays and can run on batteries for years.
The 9-volt was purely to maintain the time across power outages, e.g., so that, if you unplugged it and moved it somewhere else, you wouldn't need to set it when you plugged it back in. Without AC, it was non-functional as a clock or as an alarm clock.
Interesting
“Without AC, it was non-functional as a clock or as an alarm clock.”
That is false. The Air India flight was blown out of the sky using the same type of Radio Shack Micronta alarm clock by using a lantern battery as the power source, instead of the 9V battery. If the boy was used as a means of conducting a dry run to test security measures at a typical Texas school, then no explosives or batteries were required to complete the task of introducing a dummy IED to see what would happen. The next IED brought into a school may not be a dummy.
