Can you explain this script ?

Hi:
Can you explain this script ?

#!/usr/bin/awk -f

$0 !~ /^ / {
time = $1;
print;
}

$0 ~ /^ / {
print time substr($0, length(time) + 1);
}

Thank you.

print the current record, replacing the first "length of string stored
in the variable time' characters by the value of "time".

If the first character in the input line is not a space, store the first
field in the variable "time".

If the first character is a space, print the value of time, followed by
the rest of the line.
