FYI: the "Absolute" date style uses the short date format for your region as configured in System Settings > Regional Settings > Formats. The time format you suggest is provided by the "Default (C)" option.

editing /etc/env.d/02locale adding: LC_TIME="C" editing ~/bashrc adding: export LC_TIME="C" restarted the system
