From <https://github.com/shadow-maint/shadow/pull/71>: ``` The third field in the /etc/shadow file (sp_lstchg) contains the date of the last password change expressed as the number of days since Jan 1, 1970. As this is a relative time, creating a user today will result in: username:17238:0:99999:7::: whilst creating the same user tomorrow will result in: username:17239:0:99999:7::: This has an impact for the Reproducible Builds[0] project where we aim to be independent of as many elements the build environment as possible, including the current date. This patch changes the behaviour to use the SOURCE_DATE_EPOCH[1] environment variable (instead of Jan 1, 1970) if valid. ``` This updated PR adds some missing calls to gettime (). This was originally filed by Johannes Schauer in Debian as #917773 [2].
