Does awk have a function to determine the previous day?
 
Hi

No, regular [tt]awk[/tt] can not, only [tt]gawk[/tt] has date handling functions :
Code:
print "Today is",strftime("%c",systime())
print "Yesterday was",strftime("%c",systime()-60*60*24)
Your simplest solution would be to ask the [tt]date[/tt] command :
Code:
"date" | getline d; print "Today is",d
"date -d yesterday" | getline d; print "Yesterday was",d
Tested with [tt]gawk[/tt] and GNU [tt]date[/tt].

Feherke.
