Database is UTC, my python code:
import sqlite3
import csv
import sys
conn = sqlite3.connect('/home/talo.db')
cur = conn.cursor()
data = cur.execute('select time, value from talo_data where position_id=1 AND DATETIME([time]) >= DATETIME("now","-1 day");')
with open('/home/log/my.csv', 'wb') as f:
writer = csv.writer(f)
writer.writerow(['date', 'value'])
writer.writerows(data)
for row in data:
print >> f, row
my csv file UTC, must be local time:
date,value

In short use datetime.datetime.strptime(str, fmt)
>>> (datetime.datetime.strptime('2013-08-11 06:10:00,179375', "%Y-%m-%d %I:%M:%S,%f")+datetime.timedelta(hours=3)).strftime('%Y-%m-%d %I:%M:%S,%f')
In long this will be a three step process:-
