We've discussed this before (see below). The configuration is intentionally like that. I specifically configured skate and snapper to build the exact same source, where skate builds with default buildfarm settings, while snapper builds with the settings actually used by Debian source packages. These animals were set up to avoid cases we had in the past where Debian source packages failed to build on sparc, even though build animals running on Debian sparc were building fine: https://www.postgresql.org/message-id/000001d2f0c2%24e2d335a0%24a879a0e0%24%40turelinckx.be With snapper building the exact same source as skate (as it is now), we have some point of reference if snapper fails but skate succeeds. I could configure snapper to perform an update of the repo before building, but then we give up this comparability in exchange for a bit more clarity regarding timestamps.
