Subject: tests/example: Reset times of (copied) source files too
X-Git-Tag: subdirmk/0.3~79
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ian/git?p=subdirmk.git;a=commitdiff_plain;h=2c590a124e0d566790f756cad4872f13e2c9aa0a

tests/example: Reset times of (copied) source files too

This eliminates a problem with our test case: if the build takes less
than 1s the files were probably copied more recently than the 1s ago,
resulting in too much rebuilding (and possibly missing
failed-to-rebuild bugs).

We can now change the timestamp for the build tree to something
earlier.
