Package: graphviz Version: 2.42.2-4 Severity: normal Tags: patch User: reproducible-bui...@lists.alioth.debian.org Usertags: timestamps X-Debbugs-Cc: reproducible-b...@lists.alioth.debian.org
When built on machines with different timezones, many of the .pdf files in the graphviz packages embed a different date. There is already support in the code for using SOURCE_DATE_EPOCH, which is great! It also needs pass the "-gmt True" argument when rendering the time in order to ensure the system timezone doesn't change the result. Patch attached which does this. Thanks! live well, vagrant

Subject: [PATCH] gv_doc_template.tcl: Pass "-gmt True" to support reproducible
dates.
While the code already uses SOURCE_DATE_EPOCH, it also needs to ensure
that the times are emitted in UTC/GMT, otherwise building on machines
configured with different timezones may result in different embedded
timestamps.
