traintracks

Punch card for tracking times when a train passes by the office.

I recently moved to a new office building sandwiched between a busy intersection and some train tracks. I want to find a pattern for when the train comes by, and no schedule is available (it's not a passenger train). It occurred to me to leverage github's punchcard graph to visualize this data. Whenever I hear the train come by, I'll just run punch.sh, which will log the current time to punchcard.txt and commit it with the same timestamp.

Examples

By default, punch.sh uses the current timestamp returned from date.

$ ./punch.sh
[master 84682a7] Fri Jan 16 10:14:55 CST 2015
 1 file changed, 1 insertion(+)

But you can specify anything that date can parse.

$ ./punch.sh "1/15 13:42"
[master a05d944] Thu Jan 15 13:42:00 CST 2015
 1 file changed, 1 insertion(+)

$ ./punch.sh 3:14pm
[master 5bacaaa] Fri Jan 16 15:14:00 CST 2015
 1 file changed, 1 insertion(+)

$ ./punch.sh 9
[master 3e9cb8c] Fri Jan 16 09:00:00 CST 2015
 1 file changed, 1 insertion(+) 

Reusability

There's nothing train-specific about this code. Fork the initial commit and you'll have a fresh punch card to track whatever you like!
