Hi,
Whilst working on the Reproducible Builds effort [0] we noticed that
critcl could not be built reproducibly.
This is because the teapot.txt files contain the current build date:
│ │ ├── ./usr/lib/tcltk/x86_64-linux-gnu/critcl_callback1/teapot.txt
│ │ │ @@ -1,10 +1,10 @@
│ │ │ Package critcl::callback 1
│ │ │ Meta platform linux-glibc2.30-x86_64
│ │ │ -Meta build::date 2021-07-26
│ │ │ +Meta build::date 2020-06-24
│ │ │ Meta generated::by {critcl 3.1.18} root
│ │ │ Meta generated::date critcl
A patch is attached that updates these values in the Debian binary
package from the SOURCE_DATE_EPOCH [1] variable instead, but we could
also patch critcl.tcl to use this variable directly (which could go
upstream):
3980 dict set v::code($file) config package build::date \
3981 [list [clock format [clock seconds] -format {%Y-%m-%d}]]
3982
