Brad Bishop | d7bf8c1 | 2018-02-25 22:55:05 -0500 | [diff] [blame] | 1 | The compiled .pyc files contain time stamp corresponding to the compile time. |
| 2 | This prevents binary reproducibility. This patch allows to achieve binary |
| 3 | reproducibility by overriding the build time stamp by the value |
| 4 | exported via SOURCE_DATE_EPOCH. |
