RE: [U2] Time/Date as a single number
In that case I think I'd go with the concatenation option: DATE()"R%5" : TIME()"R%5" At least that'll get you up to October 14, 2241.

Re: [U2] Time/Date as a single number
I worked on a Security Monitoring system for years and the best date/time schema is (DATE()*86400)+TIME() It's incredibly useful when detecting time differences between 2 times that may or may not cross a day boundary. It was never meant to be an alternative to the DATE() and TIME() functions alone. The DATE()-1 concept would mean that you're trying to replace the DATE() method and you're correct. With the method mentioned above, it really doesn't matter as long as its consistent because the date expressions. During my time when using the method above, it never was a replacement for the actual date and time of an occurrence. It was simply used to derive the time 'difference' as many signals, alarms and incidents in the security monitoring business are time sensitive, ie received 2 signals within 15 minutes, which could obviously cross midnight.

Goo'day, George, At 17:31 12/09/06 -0400, you wrote: I'm limited to 10 characters, and to a barcode that will only use 0-9. Problem is one of the 10 characters will need to be a basic checksum, which drops me to 9 numbers. (this can't change it's the way the bar code reader/decoder is setup). I figured 86400, from 60 sec * 60 min * 24 hours I could cheat a little, since none of the dates would be before Oct 2006. But it doesn't leave me much room. I really don't know what the upper date limit will be (I'd like to be able to work with 10 years at a min.) which is 3660 * 86400 = 31622400, which works. I think I have it worked out, but it's messy using all kinds of bit manipulation and packing, hoping it's not too slow. Would you achieve anything by setting a base at, say, 1st October, 2006 and simply using your 10 years of seconds (about 316,000,000) or even more, as an add-on to that?That gives about 30 years. That way you've got 9 digits or less, and no packing/unpacking, etc... For example, 1st October is day 14154, a seconds count of 12345657 = 205760 minutes = 3429 hours = 142 days which gives day 14295 = 19th Feb, 2007. A seconds count of 987654321 (9 digits) = 16460905 minutes = 274348 hours = 11431 days = day 25584 = 16th Jan 2038..

I suppose it depends whether you want to be able to do accurate maths with multiple date/time values. If not, I'd probably go with DATE():".":TIME() (or DATE()-1:".":TIME()). If you need to be able to do calculations with these numbers and come up with accurate intervals as a result then you'd need to either multiply the DATE() component as has been suggested, or divide the TIME() component. Personally, I'd go with the "divide the time component" option: DATE()+(TIME()/86400).

Re: [U2] Time/Date as a single number
In my application, I add a constant (134408) to the date so that it is always > 0. Then I right-justify and zero-fill to a constant length both date (plus constant) and time and delimit them with a literal ":". This gives me a non-numeric string with a constant length by which I can sort if need be. FWIW, the constant 134408 works with dates back to 1-Jan-1600.

RE: [U2] Time/Date as a single number
You can concatenate both numbers : Datetimefield = date() 'MR%5':time() 'MR%5' And then Idate = Datetimefield[1,5] And Itime = Datetiefield[6,5] I hope it works.

RE: [U2] Time/Date as a single number
>My method is take date()*86400+time() If this is UV, I believe that SYSTEM(99) returns seconds since 01-01-1970. Right now on my system, and for a long time to come, it is returning a 10 digit number.

RE: [U2] Time/Date as a single number
>My method is take date()*86400+time() Is the goal to track a chronology via a single field? If so, I'd say your calulation is close. Wouldn't it be: ((DATE() - 1) * 86500) + TIME() (...as the number of days elapsed is today - 1, not today.) Regardless, you're right that the date could get humongous. For the cycles you're going through to do this calculation it would be a small step to convert it into and out of any other base to compress and decompress the bytes. The foundational question, however, is one of context. Why do you need this? That answer may limit or expand your options. -Kevin [EMAIL PROTECTED] http://www.PrecisOnline.com ** Check out scheduled Connect! training courses at http://www.PrecisOnline.com/train.html. --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
