I remember in DOS that the OS had no concept of what timezone it is running in, so it could not base the epoch in UTC (nee GMT). That might be true for older systems in general, and might be the case for embedded systems.

It may work on every machine he tried it on, but he's still relying on emperical "happens to be implemented that way" functionality, not on specified, guaranteed functionality. IOW, it's "non-portable".

There's nothing wrong with that; you just need to be aware of its limitations. E.g. re-qualify on any new platform.
