linux - Samba modifies "last modification date" of files substracting 3 hours -


i think weird , despite having done searching wasn't able find info related problem.

i'm setting backup server raspberry pi running raspbian communicate windows 7 pc. did program auto mounting external drive attached pi, after doing manual backup of files w7 pc. shared said mounting folder on samba , works great.

the thing want use program called synkron on windows can monitor 2 or more folders, detec changes , copy on new/modified files periodically. however, when press "analyze", programs lists files (in ext drive) obsolete, , i've discovered problem samba (or pi itself) changing last modified date of files, substracting 3 hours each of them. when remove drive pi , re analyze connected pc files normal , show ok.

this exact situation has happened 2 different sets of raspberrys, raspbian installations, external drives, windows pc , files. also, checked date on both pi's , correct every time.

what do? :/

the raspberry pi doesn't have rtc, every time loses power clock reset. pi relies on network time reset everytime boots. pi have connected internet happen.

also, make sure pi configured same timezone located in. can configure going through rasp-config settings in terminal.

additional samba config options:

"time synchronization can important programmers. useful group of settings consists of following options:"

[global]     time server = yes     dos filetimes = yes     fake directory create times = yes     dos filetime resolution = yes     delete readonly = yes 

if above fails, try additional parameters:

[data]     fake directory create times = yes 

and if still, manually adjust time offset:

[global]     time offset = 1800 

warning: above has potential break after windows adjusts daylight savings time.

good luck.
