You could extract that from METALOG. If something is built twice, it will have two entries in METALOG, but only one entry in METALOG.sanitised.

Depending on the host platform, there might not be any timestamps in METALOG. On a NetBSD host, I see time= keywords in METALOG, but on a Linux host, I do not see them.
