Extracting Time From Multiple Lines of Data 2

[thunderkid]

I would like to extract time from last records from data set shown below:

input
abc 0:01:10.0 rtyh jdkrd
abc 0:01:30.0 rtyh jdkrd
abc 0:01:60.0 rtyh jdkrd
abc 0:02:10.0 rtyh jdkrd
abc 0:03:00.0 rtyh jdkrd

desired output
abc 0:03:00.0 rtyh jdkrd

Sorry for not explaining the whole context for this task. There are thousands of line within the files and I will have to make multiple extractions. For example:

nput
abc 0:01:10.0 rtyh jdkrd
abc 0:01:30.0 rtyh jdkrd
abc 0:01:60.0 rtyh jdkrd
abc 0:02:10.0 rtyh jdkrd
abc 0:03:00.0 rtyh jdkrd
def 0:03:01.0 erte wfe5
def 0:04:10.0 erte wfe5
def 0:05:01.0 erte wfe5
def 0:05:30.0 erte wfe5
def 0:06:03.0 erte wfe5
.
.
.

desired output
abc 0:03:00.0 rtyh jdkrd
def 0:06:03.0 erte wfe5
.
.
.

Try and adapt the following code :
[tt]
awk '
$1 != prv1 { if (last_line != &quot;&quot print last_line }
{ prv1 = $1; last_line = $0 }
END { if (last_line != &quot;&quot print last_line }
' input_file
[/tt]

nawk '
{ a[$1]=$0 }
END {
for (i in a)
print a;
}
' input
