Time measurement formats
Many years ago (1975)I was working with a physcist doing chemical
research. We used a time format that measured time from the begining of the year? experiment? . (Obviously from all the "?"s I can't remember.) But it was a long number that contained about 12 digits. (more memory loss) From that confused description above can anyone tell me the name of that format. I can't find anything with Google that looks anything like it.

(more memory loss) From that confused description above can anyone tell me the name of that format. I can't find anything with Google that looks anything like it. It could be just about anything. One common format used in spreadsheets is "floating point", which isn't really floating point - it has an integer part for year, month, and day, and a fractional part, which is the portion of the day from 0000 hours, expressed as a decimal fraction. You can get as fine of precision as you want, although 1 second is approximately 0.000015740_740_ of a day (1/86400), where the '740' repeats. If you want, say, microseconds resolution, then you might just want to keep a count of microseconds from T0, and resolve it into YYYYMMDDHHMMSSMMMUUU format in software. Good Luck! Rich |
