Modify time anomality

Without calling flush the modify-time of the two files will be the same. Even if we sleep 0.001 seconds. Despite the fact that the filesystem provide more accurate values.

If we we wait a bit between calls, or if we flush the buffer of the file, then the timestamps will be different.

import os
import time

with open("first.txt", "w") as fh:
    fh.flush()
    pass
print(f"time: {time.time()}")
#time.sleep(0.01)
with open("second.txt", "w") as fh:
    pass
first = os.path.getmtime("first.txt")
second = os.path.getmtime("second.txt")
print(first)
print(second)
print("same" if first == second else "diff")
