Re: HELP WITH DATES
This WebDNA talk-list message is from 1997
It keeps the original formatting.
numero = 10457
interpreted = N
texte = >Will it be able to deal with my preferred YEAR/MONTH/DAY format (as in >1997/04/23) instead of just understanding MONTH/DAY/YEAR?It looks at the preferences for date format (which until now has only referred to your preference for OUTPUT) and deduces from that what the date input format should be.>How is it going to detect whether or not there's a date in the math >context? In other words, what's it looking for that makes it decide that >it's dealing with a date instead of a text string? Just the slashes? Or two >slashes separated by two other characters? or ???It looks for sequences of numbers like xx/xx/xx and assumes that is a date. So you _cannot_ create a math context that has 2 divisions in a row. If you use parentheses you could create the 2 divisions.I am leaning toward a WebDNA assumption that if there's a date in the math context anywhere, then it is assumed that the results of the math context will look like a date instead of a number.[math]12/3[/math] yields 4 [math]12/3/96+1[/math] yields 12/4/96 [math]12/3/96+0/0/1[/math] yields 12/3/97The whole idea here is to make the syntax for date manipulation a lot easier. Currently you can do it, but it takes a lot of [ConvertDate] stuff, and all numbers are in seconds. So the second line above reads (in b12 WebDNA):[format date][math][convertdate]12/3/96[/convertdate]+86400[/math][/format]Which is the same thing, except it forces you to know there are 86400 seconds in a day.Grant Hulbert, V.P.

[math]12/3/96+1[/math] yields 12/4/96
