Here's the change in the development snapshot:
"Today’s Mini vMac Development source snapshot adds the new build system options “-alc, -lcy, and -lcx” to allow manually setting the location fields in the Parameter RAM, and the options “-atz, -lcd, -lczs, and -lcz” to allow manually setting the time zone fields.
The “GetPRAM” tool has been updated to support these location and time zone options.
These Parameter RAM fields are not much used. Two example programs that can use the location fields are MacAstro and Star Atlas."
