Modifier automatiquement l'heure en fonction de l'emplacement actuel

Je me déplace souvent entre 2 fuseaux horaires et je m'attends à ce que mon ordinateur portable Windows 7 modifie automatiquement l'heure du système, étant gâché par la même fonctionnalité sur mon téléphone portable. J'ai toujours supposé que le bureau O / Ses ne faisait tout simplement pas cela, mais j'ai été choqué hier quand j'ai remarqué que OSX sur le MacBook le faisait réellement!

Quelqu'un sait -il de tous les services publics qui fait cela sur Windows, en particulier Windows 7? Il doit y avoir quelque chose là-bas?

J'en ai eu assez de changer l'heure de mes voyages et j'ai juste décidé de construire le produit.

Alors maintenant, il existe un logiciel pour cela: je l'ai appelé TimeTraveller et vous pouvez le trouver sur http://www.godotandco.com

Cela m'a ennuyé après la mise à niveau vers Windows 8.1; J'espérais qu'il ferait quelque chose comme le Mac. J'ai donc passé quelques heures à créer mon premier script PowerShell pour le faire. Jusqu'à présent, cela fonctionne.

N'hésitez pas à télécharger et à utiliser (instructions incluses).

Je n'ai trouvé aucun logiciel SW pour le faire automatiquement en fonction de l'emplacement, donc au moins pour simplifier la tâche, j'ai créé un petit fichier de commandes à l'aide de l'utilitaire de ligne de commande tzutil dans Windows 7. Pour s'adapter, vous devez vérifier les noms de fuseau horaire tzutil (tzutil / l)

@ECHO OFF
ECHO 1. Greece (UTC+2)
ECHO 2. CET (UTC+1)
CHOICE /C:12 /M "Set Time Zone "
IF ERRORLEVEL 2 GOTO TWO
IF ERRORLEVEL 1 GOTO ONE
:ONE
tzutil /s "GTB Standard Time"
GOTO END
:TWO
tzutil /s "W. Europe Standard Time"
:END

Voici un script Powershell modifié mis à jour de l'utilisateur ### qui a lié à pastebin dans sa réponse, cela fonctionne.

Si vous êtes sur un réseau d'entreprise, cela aura encore plus de problèmes. À moins que le système ne dispose d'une puce GPS intégrée permettant d'obtenir son emplacement et son fuseau horaire précis, il déterminera son emplacement par son IP publique et sa géolocalisation IP. Sur un réseau d'entreprise, cela sera toujours déterminé par le contrôleur de domaine, qui est généralement géographiquement dans un emplacement statique.

Si votre système n'est pas sur un domaine, le recours à l'IP publique et à la géolocalisation sera toujours problématique si vous êtes près d'une limite de fuseau horaire, car vous ne savez jamais si votre IP est distribuée par un serveur sur la ligne.

Il peut être plus facile d'écrire un peu de code qui s'exécute dans la barre d'état système et vous permet de sélectionner simplement le fuseau horaire approprié, puis de mettre à jour votre horloge système en conséquence.

Microsoft dispose d'un outil de fuseau horaire qui vous permet de définir et d'afficher plusieurs fuseaux horaires. Je n'ai pas vérifié pour voir à quel point il est facile de basculer entre les favoris comme votre zone actuelle, mais cela peut être un pas dans la bonne direction.

vous devrez obtenir un logiciel pour cela, car je ne connais pas d'autre moyen pour que cela fonctionne dans Windows ( car la configuration de NTP ne sera pas affectée par les changements de fuseau horaire ) et vous pouvez essayer Atomic Clock Sync .
