Then I'd suppose that first archive (the one shown on the left size) was
created in ustar, gnu or similar format - the one that stores timestamps
with a seconds precision.  In contrast, second archive (the one shown on
the right side) is in POSIX.1-2001 format, which stores timestamps with
a subsecond precision.
