From e27c8969982e970d714cfa469f179bed5000494b Mon Sep 17 00:00:00 2001 From: "Bernhard M. Wiedemann" Date: Sun, 18 Nov 2018 08:14:50 +0100 Subject: Use cmake TIMESTAMP function because it is not only platform independent but also allows to override the build date This helps to make tigervnc builds reproducible See https://reproducible-builds.org/ for why this is good Also adds UTC flag, to be independent of timezone. Also changes JAVA_DATE format to ISO-8601 date format.
