3 бесплатное программное обеспечение для синхронизации времени для Windows 10/8/7
Если ваша Windows не синхронизирует системное время правильно, используйте эти бесплатные программы, чтобы заставить Windows синхронизировать время при каждом запуске. По умолчанию Windows 10/8/7 периодически синхронизирует ваше системное время с интернет-серверами. И это хорошо работает. Но есть пользователи, которые сообщают, что синхронизация времени завершилась неудачно, потому что служба времени Windows не работала или что системное время Windows возвращается назад. Если вы столкнулись с этой проблемой, вы можете рассмотреть возможность использования бесплатного программного обеспечения синхронизации времени в вашей системе Windows.
Одно решение для трех задач
Решение по защите и управлению данными сервера для следующего сценария:
Резервное копирование всех ваших критически важных данных с серверов и рабочих станций на ваш файловый сервер. Несколько вариантов резервного копирования обеспечивают полное дублирование данных и простоту восстановления. Исключительная легкость в развертывании и использовании.
Храните данные ваших файловых серверов в синхронизированном состоянии между критическими центрами. Обеспечьте высокую доступность и непрерывный доступ к Вашим данным через автоматическую службу синхронизации в режиме реального времени.
GoodSync Сервер позволяет копировать важные данные в любую точку. Это обеспечивает такой сервис как автоматизированная служба аварийного восстановления в реальном времени для любого сервера, NAS или облака. Гарантирует полное дублирование данных.

Перезапустите службу времени Windows.
Перезапуск службы времени Windows из диспетчера служб Windows — еще один эффективный способ синхронизации часов вашего ПК с сервером Windows. Для контекста, Windows Time Server помогает пользователям Windows поддерживать наиболее точное время на своих устройствах, активно синхронизируя дату и время с сервером времени Microsoft.
Если ваш компьютер сталкивается с проблемами с неправильной синхронизацией или всегда не синхронизируется с официальным сервером Microsoft, возможно, проблема связана со службой времени Windows, и ее перезапуск может помочь. Вот как это сделать.
Шаг 1: Нажмите одновременно клавиши Windows + R на клавиатуре, чтобы открыть диалоговое окно «Выполнить команду».
Шаг 2: Тип services.msc в предоставленное поле и нажмите кнопку ОК.
Это запустит диспетчер служб Windows в новом окне. Прокрутите страницу вниз и найдите службы времени Windows, расположенные на странице в алфавитном порядке, поэтому у вас не должно возникнуть проблем с их поиском.
Затем включите эту службу или убедитесь, что она включена и работает правильно. Поскольку, как предупреждает Windows, синхронизация даты и времени будет недоступна, если служба времени Windows остановлена или отключена.
Шаг 3: Щелкните правой кнопкой мыши службу времени Windows и выберите Пуск.
Если служба времени Windows была включена и работает, но время вашего ПК по-прежнему неверно или не синхронизируется с сервером времени Microsoft, вам следует перезапустить службу. Щелкните правой кнопкой мыши Windows Time и выберите «Перезагрузить».
Шаг 4: Перезагрузите компьютер.
После перезапуска вы также хотите убедиться, что ваше устройство подключено к активному интернет-соединению (Wi-Fi или Ethernet-кабель).

Targeted ads from third-party apps
Microsoft is definitely keeping tabs on your preferences and browsing habits in Windows 10. You even have a unique advertising ID (tied to your Microsoft account), which the company uses to show you targeted ads. Oh, and Microsoft also shares this advertising ID profile with third-party apps from the Windows Store, unless, of course, you turn this information sharing off.
You can turn this off by going to Settings > Privacy > General > Let apps use advertising ID to make ads more interesting to you based on your app activity (Turning this off will reset your ID).

Radio Station WWV
Beginning November 15, 2021, WWV and WWVH will be broadcasting a test signal on minute 8 of each hour on WWV, and minute 48 on WWVH. This signal has been created to assist in ionospheric research, and is a joint effort of the Ham Radio Citizen Science Investigation (HamSCI) and NIST. The signal consists of various tones, chirps, and Gaussian noise bursts. The signal may be modified occasionally. For more information on HamSCI and the WWV/WWVH project, click here.
NIST radio station WWV broadcasts time and frequency information 24 hours per day, 7 days per week to millions of listeners worldwide. WWV is located near Fort Collins, Colorado, about 100 kilometers north of Denver. The broadcast information includes time announcements, standard time intervals, standard frequencies, UT1 time corrections, a BCD time code, and geophysical alerts.
Broadcast Frequencies
WWV operates in the high frequency (HF) portion of the radio spectrum. The station radiates 10 000 W on 5 MHz, 10 MHz, and 15 MHz; and 2500 W on 2.5 MHz and 20 MHz. Each frequency is broadcast from a separate transmitter. Although each frequency carries the same information, multiple frequencies are used because the quality of HF reception depends on many factors such as location, time of year, time of day, the frequency being used, and atmospheric and ionospheric propagation conditions. The variety of frequencies makes it likely that at least one frequency will be usable at all times.
Antennas
The WWV antennas are half-wave vertical antennas that radiate omnidirectional patterns. There are antennas at the station site for each frequency. Each antenna is connected to a single transmitter using a rigid coaxial line, and the site is designed so that no two coaxial lines cross. Each antenna is mounted on a tower that is approximately one half-wavelength tall. The tallest tower, for 2.5 MHz, is about 60 m tall. The shortest tower, for 20 MHz, is about 7.5 m tall. The top half of each antenna is a quarter-wavelength radiating element. The bottom half of each antenna consists of nine quarter-wavelength wires that connect to the center of the tower and slope downwards to the ground at a 45 degree angle. This sloping skirt functions as the lower half of the radiating system and also guys the antenna.
WWV Antenna Coordinates
| Frequency (MHz) | Latitude | Longitude |
|---|---|---|
| 2.5 | 40° 40′ 55.2″ N | 105° 02′ 31.3″ W |
| 5 | 40° 40′ 42.1″ N | 105° 02′ 24.9″ W |
| 10 | 40° 40′ 47.8″ N | 105° 02′ 25.1″ W |
| 15 | 40° 40′ 45.0″ N | 105° 02′ 24.5″ W |
| 20 | 40° 40′ 53.1″ N | 105° 02′ 28.5″ W |
Modulation
The signals broadcast by WWV use double sideband amplitude modulation. The modulation level is 50 percent for the steady tones, 50 percent for the BCD time code, 100 percent for the second pulses and the minute and hour markers, and 75 percent for the voice announcements.
Experimental 25 MHz WWV Broadcast
WWV has resumed broadcasting on 25 MHz on an experimental basis. The broadcast consists of the normal WWV signal heard on all other WWV frequencies, at the same level of accuracy.
Current 25 MHz Broadcast Specifications
Schedule: typically continuous. As an experimental broadcast, the 25 MHz signal may be interrupted or suspended without notice.
Radiated Power: 2.5 kW
Antenna: half-wave vertical dipole.
