Function: ElapsedTime_CFpub ( tsStart ; tsEnd).
Type: Timestamp calculation returning a text result.
Purpose: To calculate in human readable form the elapsed time between two events using years, months, days, hours, minutes and seconds.
Constraints: The function uses 30 days for months and 12 months for years resulting in a 360 day year.
Options: The function can be rewritten without the years and months and is perfectly accurate for elapsed time vs calendar time.
Modifications: The function can have a third parameter to extract any one time period value or to supply the text form.

Lee, perhaps the date on your birth certificate is wrong. :)
Actually, you are right. I got some weird results when using this CF, so I re-wrote it.
Cheers.
