2018 Resolution #1: Standardize to 24-hour time
A year or so ago, one of my resolutions was to finally iron out the problem of writing dates. For context: I grew up in Australia, where the default is DD/MM/YY. But in the US, where I now live, the default is MM/DD/YY. Now if I had to pick one of the two, I would probably lean towards the former, since it seems slightly more logical, and more natural to me personally. But since everyone around me uses the latter, taking that avenue would only cause more confusion in my life, perhaps not for me, but certainly for those around me.
For a while I would switch between the two systems depending on what purpose I was writing the date for. Items such as school assignments would be dated in the American fashion, while things for my personal consumption would be done in the commonwealth manner. Until after several years I started going throug my own files of schoolwork, particularly artwork, and encountering dates such as 9/10. What does that mean, in the context of a pencil marking in the corner of a sketch, jotted down as an afterthought? Does it mean the tenth of September, or the ninth of October? Or was it completed during the month of September, 2010? Or perhaps it is merely the ninth piece of a series of ten? Or perhaps it received a score of 90% that I wanted to record for posterity.
I knew that the dualistic system was untenable, but I also knew that I would likely fail in the mental self-discipline necessary in forcing myself into either of the two competing standards; especially given that there remain certain contexts where it is necessary that I use each. I therefore decided to adopt a whole new system, based on ISO 8601.
Henceforth, where I was given the choice, I would record all dates in YYYY-MM-DD format. This would make it abundantly obvious that I was recording the date, and the format I was using. It was also different enough that I would not confuse it. Where compelled by outside forces, such as stringent academic standards for school assignments, I would continue to use the other formats, but there it would be clear which format I was using.
Despite skepticism from those around me, this system has worked out quite well, and so I am expanding the project to include having time displayed on my devices in 24-hour time.
