If the SOURCE_DATE_EPOCH environment variable is set, returns it’s value. Otherwise, returns the time that ‘Gem.source_date_epoch_string` was first called in the same format as SOURCE_DATE_EPOCH.
NOTE(@duckinator): The implementation is a tad weird because we want to:
1. Make builds reproducible by default, by having this function always return the same result during a given run. 2. Allow changing ENV['SOURCE_DATE_EPOCH'] at runtime, since multiple tests that set this variable will be run in a single process.
If you simplify this function and a lot of tests fail, that is likely due to #2 above.

Call the free function for this pointer. Calling more than once will do nothing. Does nothing if there is no free function attached.
Read a REG_SZ or REG_EXPAND_SZ registry value named name.
If the value type is REG_EXPAND_SZ, environment variables are replaced. Unless the value type is REG_SZ or REG_EXPAND_SZ, TypeError is raised.
Read a REG_SZ(read_s), REG_DWORD(read_i), or REG_BINARY(read_bin) registry value named name.
If the values type does not match, TypeError is raised.
If stat is readable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).
m = File.stat("/etc/passwd").world_readable? #=> 420 sprintf("%o", m) #=> "644"
Returns true if stat is writable by the real user id of this process.
File.stat("testfile").writable_real? #=> true
Same as executable?, but tests using the real owner of the process.
