Fix date creation

[valtlai]

The Date constructor does not support undefined as an argument, so we must specify the default values ourselves.

Also

• allow a lowercase t as the date-time separator
• shorten the regexes by using \d\d instead of \d{2}
• reorder the comparison operators in comments to match the ones in switch–case.

The idea was to use the current time values for missing (or undefined) arguments. For example, new Date(year, month, day) creates a date with the current time (to hours, minutes and seconds). Your change forces the time to 0:00:00. Maybe it makes more sense because using the current time is a bit random...

[valtlai]

Yeah, I think it’s random. If I write date>=2021-04, I want a page with date: 2021-04-01T00:00:00 to always match, regardless of the current date or time.

Hmm, the Date constructor doesn’t seem to use the current date time for the missing values, but replaces them with default values instead, like 1 for the day of the month or 0 for hours. (I tested with Chrome, which uses the same V8 JavaScript engine as Deno. See also MDN.) Using undefined (as we’re doing with hour && parseInt(hour)) results Invalid Date.

Yes, you're absolutely right. I don't know why I've assumed that it would take the current value.
