What we need is not more ways to try to make collections of digits into a date, but something which actually refers to the date, no matter what context it's in, using the places of a bridi.
The result will be longer, but will create things which are unquestionably dates and which have clearly-specified places, instead of assuming that any number which fills a "date" place is some sort of date.
I'll use a fu'ivla, because no seljvajvo lujvo could possibly have this place structure without being entirely unwieldy. I'll base it on tcika and detri, though.
dreika: x1 is the interval of time in year x1, month x2, day x3, hour x4, minute x5, and second x6 by calendar x7
(In alternate calendars, change "month" to whatever is an appropriate intermediate interval between years and days.)
So here are some examples:
How do you express the seconds and the calendar in le dreika befo li 17 beifu li 25 ...? - Oh, le dreika befo li 17 bei li 25 bei li 13 bei...
But just seconds and calendar?
You can add a subscript to se and fa.
Right. For an example, (I'm starting to like detytcika better) {ti detytcika li 3167 faxize la diskordian.} There are other brivla which have more than 5 places - jutsi does, not to mention various seljvajvo lujvo.
I can see myself preferring "ci'e" to "faxize" in real usage. --xod
And what do you do for those who dislike type 4 fu'ivla? A non-seljvajvo lujvo is probably better than the creation (as opposed to the evolution of) a type 4 fu'ivla. And it's embarrassing to have to import a word for the idea of "timestamp".
I use the names of months with the place structure "x1 is (e.g.) December of year x2". It's not a jvajvo, but it makes it possible to say a date verbosely. --phma
Also, shouldn't this be Date/Time bridi valsi or Date/Time brivla? It isn't usually a whole bridi.
