The compression utility dictzip writes the compressed file's mtime in a header
|
|
of the compressed file. No command-line switch is documented to control or
|
|
suppress this behavior. This makes the build of packages relying on
|
|
freedict-tools such as freedict-dictionaries non-deterministic.
|
|
|
|
This patch sets the mtime of the .dict file to be compressed by dictzip to the
|
|
start of the epoch on the Greenwich meridian, restoring build determinism.
