California earthquake alarm sounded – 92 years late

It doesn't seem that implausible for a program to be reading through a dataset and issue a notice for a measurement above some value. If the dataset encoded years in just two digits, it (almost) makes sense that the program would report it 100 years off.

Imagine:

    with open(file) as f:
        for record in f:
            year, month, day, time, magnitude = record.split()
            
            if magnitude > 5:
                raise_alarm()

Global alerts are pretty infrequent, so it doesn't hurt to sign up for this if it's something you have a passing interest in.
