    How to sync NTP time with systemd-timesyncd

    systemd-timesyncd is a system service in Linux operating systems that provides time synchronisation with NTP servers. It continuously adjusts the system clock to ensure accurate timekeeping, which is crucial for various system operations, time-sensitive applications, and network synchronisation.

    To configure systemd-timesyncd, edit file

    vi /etc/systemd/timesyncd.conf

    Add following

    [Time]
NTP=
FallbackNTP=time.google.com

    Leaving NTP= uncommented and assigned to an empty string resets the list of NTP servers, including any per-interface assignments. This prevents inadvertently moving between smeared and un-smeared time servers. Configuring Google Public NTP as the fallback server will cause it to be selected as the only NTP server.

    If you want to use debian maintained NTP servers, use

    [Time]
NTP=
FallbackNTP=0.debian.pool.ntp.org 1.debian.pool.ntp.org 2.debian.pool.ntp.org 3.debian.pool.ntp.org

    Restart systemd-timesyncd

    systemctl restart systemd-timesyncd.service

    You can verify NTP server with command

    timedatectl show-timesync | grep ServerName

    timedatectl show-timesync

    Timestamp in Bash Script

    TIME_STAMP="$(date +%Y%m%d-%H%M%S)"

    for timestamp like 2020-01-23 15:12:45, use

    TIME_STAMP="$(date "+%Y-%m-%d %H:%M:%S")"

    For file name

    date +"%Y-%m-%d-%H-%M-%S"

    Time stamp in PHP

    $now = date("Y-m-d-h:i:s");

    Taking backup

    mysqldump -u root -p'mv9wCAcDE3CnBV' serverok_wp > ~/serverok_wp-`date +"%Y-%m-%d-%H-%M-%S"`.sql
