+Subject: [PATCH] robottime: Honor the SOURCE_DATE_EPOCH environment variable.
+
+Honoring the SOURCE_DATE_EPOCH environment variable allows building
+the documentation using libdoc reproducibly, by setting the generated
+timestamp to a fixed value.
+
+For more background on reproducible builds and the SOURCE_DATE_EPOCH
+environment variable, see:
+https://reproducible-builds.org/specs/source-date-epoch/.
+
+* src/robot/utils/robottime.py: import `os'.
+(TimestampCache._get_epoch): Retrieve date from SOURCE_DATE_EPOCH if
+it is defined, otherwise from time.time().
+* utest/output/test_logger.py (TestLogger.test_write_to_one_logger):
+Check for the existance of a timestamp attribute instead of checking
+for its content as the later is easy to break when using the
+SOURCE_DATE_EPOCH environment variable.
