>Description:
By default, /usr/bin/time writes its output to stderr. Two options
have been added to time(1) to write output to an alternative destination.
Option "-f filename" will write to filename, and filename can be - to
write to stdout. Option "-a filename" will append the output to filename.
Time(1) man page has been updated to reflect the change.
