[REQ] Datetime variables with custom format

[ItsDrike]

I would love to see an option to customize the format of the $TIME (like for including seconds), and a way to also show the current date, where a customizable format is pretty much necessary as there's different standards for that in different countries.

One way to handle this would be to just add a $DATE variable, and to take the format options for both as options in the config.
Another would be to create a more complex system which would allow specifying the format in the variable, like say $DATETIME[%HH:%MM:%SS]. This option would be better in case someone wanted to show the time multiple times with different formats, but it'd probably be much more complex to actually implement.

This could probably also be solved through #29, if it gets addressed, using the date command.

Not sure if this is still relevant since we now have commands, and can just do text = cmd[update:200] date +'%H:%M:%S' . It'd still be a bit nicer and bit easier to use maybe, but not sure it'd be worth the hassle to implement. Feel free to close.

The only annoyance with using cmds to show time is you can't use 1s update intervals, since the interval doesn't start at a "whole" second, so it could sometimes skip by 2 seconds, which looks bad.

btw for those who on arch, u can use:

enable strftime; strftime '%T' $EPOCHSECONDS

instead of date. spawning not-so-light date every second or even 0.5 very inefficient
