You can create a script input that will remember where it left off and print the difference.
Below is an example script
import hashlib
from datetime import datetime, timedelta
from itertools import islice
from re import search
log_file="sample.log"
try:
with open(hashlib.sha256(log_file.encode()).hexdigest()) as state:
last_position=int(state.readline())
except IOError:
last_position=0
data_pattern = r"^(\d+\.\d+) (.+)$"
date_pattern = r"^\d+\.\d+ (\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2})"
with open(log_file, 'r') as f:
data=search(date_pattern, f.readline())
datetime_object = datetime.strptime(data.group(1), r'%Y-%m-%d %H:%M:%S')
f.seek(last_position)
for line in f:
data = search(data_pattern, line)
if data is not None:
print('{} {}'.format(
datetime_object+timedelta(seconds=float(data.group(1))),
data.group(2)))
last_position=f.tell()
try:
with open(hashlib.sha256(log_file.encode()).hexdigest(),'w') as state:
state.write('{}'.format(last_position))
except IOError:
print("Error writing state file")

The idea of the script is to be expandable so that with slight modifications you can modify the script to receive parameters and keep state in a convenient location
