No, though that's also a possibility, but a backward-incompatible one.
What I mean is have a well-defined 64-bit timestamp for each block, but
only put the lowest 32 bit in the header. Under the condition:
* There is never a gap of more than 136 years between two blocks.
The actual 64-bit timestamp can be deterministically derived from the
header, by prefixing it with the lowest 32-bit value that does not
cause the result to violate the
at-least-above-the-median-of-the-previous-11-blocks rule.
