Tasks​

  1. Set timezone to Singapore time.
  2. Manually set time to 5 minutes ahead.
  3. Verify time sync is active. Observe NTP.

Solution​

1. Set timezone to Singapore time.​

Before setting the timezone, check the current timezone settings:

timedatectl

Set the timezone to Singapore:

sudo timedatectl set-timezone Asia/Singapore

Verify the timezone change:

timedatectl

Ensure that Time zone now reflects Asia/Singapore.

2. Manually set time to 5 minutes ahead.​

Use the date command to set the system time 5 minutes ahead of the current time:

sudo date --set="+5 minutes"

Verify the updated time:

date

3. Verify time sync is active. Observe NTP.​

Use timedatectl to verify if NTP synchronization is active:

timedatectl status

Look for NTP synchronized in the output. It should indicate yes if NTP synchronization is active and the system clock is synchronized with a time server.

To observe logs related to NTP synchronization, check the logs depending on your Linux distribution:

journalctl -u systemd-timesyncd.service    # For systems using systemd-timesyncd
journalctl -u ntpd.service                # For systems using NTP daemon (ntpd)
