Question

I wrote this code in c# to check if a file is out of date:

 DateTime? lastTimeModified = file.getLastTimeModified();
        if (!lastTimeModified.HasValue)
        {
            //File does not exist, so it is out of date
            return true;
        }
        if (lastTimeModified.Value < DateTime.Now.AddMinutes(-synchIntervall))
        {
            return true;
        } else
        {
           return false;
        }

How do I write this in python?

I tried this in python.

statbuf = os.stat(filename)
if(statbuf.st_mtime < datetime.datetime.now() - self.synchIntervall):
    return True
 else:
    return False

I got the following exception

message str: unsupported operand type(s) for -: 'datetime.datetime' and 'int'

You want to use the os.path.getmtime function (in combination with the time.time one). This should give you an idea:

>>> import os.path as path
>>> path.getmtime('next_commit.txt')
1318340964.0525577
>>> import time
>>> time.time()
1322143114.693798
