Determine which year to use with julian dates

[frangac]

Hi All,

Below is a script from CaKiwi,

If I am reading a file that is dated 20041225 with Julian date 360, which uses the current year (2005) to determine if it is a leap year("date +'%Y'" | getline yy), and then returns the wrong date format which I understand why this is being done.
My question is , Is there a way to determine if the year should be 2004 instead of 2005?

split("31 29 31 30 31 30 31 31 30 31 30 31",m)
"date +'%Y'" | getline yy
mm = 1
while (dd > m[mm]) {
dd -= m[mm] mm++
}
printf ("%4.4d/%2.2d/%2.2d\n", yy, mm, dd)
}

Many Thanks
Chris

I'm not sure if I fully understand your question, but if you want to get the year from the filename, replace

"date +'%Y'" | getline yy

by

yy = substr(FILENAME,1,2)

If the year is to be obtained from the creation date of the file, try something like

"ls -l" | getline
yy = $8

Hope this helps
