match_minimum_break.py

This script will report on the match schedule for every team at the 2019 Touch World Cup to determine that there has been sufficient break time scheduled between fixtures.

It will report only on games with insufficient break between them - for example:

Men's Open      Netherlands            03/05/19 08:55   03/05/19 11:40  0d 2h 45m

Women's 27 Australia 30/04/19 13:30 30/04/19 16:15 0d 2h 45m

Using a modern systemd on CentOS 7.x

Unfortunately the systemd that ships with CentOS 7.x is stalled at v219 - that is pretty old now, and there are some great features you're missing out on.

Thankfully facebookincubator/rpm-backports and https://copr.fedorainfracloud.org/coprs/jsynacek/systemd-backports-for-centos-7/ have come to the rescue!

Note: you really need to pay attention to the SELinux comment - if you don't disable it you're probably going to brick your host. Thankfully I tried this in a disposable vagrant first...

Disable SELinux
