Well, you\u2019ve got a problem because time discrepancies mean that all timestamps are inaccurate, making it impossible to correlate log files from various sources.<\/span><\/p>\n<p><span style=\"color: #000000;\">Without <strong><a style=\"color: #000000;\" href=\"https:\/\/www.galsys.co.uk\/categories\/time-synchronisation\/time-synchronisation.html\">time synchronisation<\/a><\/strong>, pinpointing the exact moment of any network security breach is difficult. <\/span><\/p>\n<p><span style=\"color: #000000;\">Plus, without an accurate time trail, presenting evidence in a court of law attempting to prove malicious activity would be difficult. Not only has your network been hacked, but those responsible are not made accountable.<\/span><\/p>\n<p><span style=\"color: #000000;\">Unsynchronised clocks can also impact automated tasks. Certain processes, like backups and transaction processing rely on accurate time, but should those processes run out of sequence there will be discrepancies because transaction times will be incorrectly recorded. Inaccurate timestamps equal financial &amp; database program errors.<\/span><\/p>\n<h2><span style=\"color: #000000;\"><strong>Time synchronisation at home<\/strong><\/span><\/h2>\n<p><span style=\"color: #000000;\">Inaccurate clocks can cause just as much trouble on home computers as they can for entire computer networks.<\/span><\/p>\n<p><span style=\"color: #000000;\">For instance, every email you send is \u2018timestamped\u2019 thanks to the local system clock used by your PC. If the timestamp on your email is overly inaccurate chances are that some email servers will deem your sent messages to be spam, especially if the date or time is in the past or future. <\/span><\/p>\n<p><span style=\"color: #000000;\">So, that important email might end up in the junk folder of the intended recipient.<\/span><\/p>\n<figure id=\"attachment_1378\" aria-describedby=\"figcaption_attachment_1378\" class=\"wp-caption aligncenter\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\" style=\"width: 600px\"><a href=\"https:\/\/www.galsys.co.uk\/news\/wp-content\/uploads\/email-time-stamp.png\"><img loading=\"lazy\" decoding=\"async\" itemprop=\"contentURL\" class=\"wp-image-1378\" src=\"https:\/\/www.galsys.co.uk\/news\/wp-content\/uploads\/email-time-stamp.png\" alt=\"time synchronisation\" width=\"600\" height=\"375\" srcset=\"https:\/\/www.galsys.co.uk\/news\/wp-content\/uploads\/email-time-stamp.png 1440w, https:\/\/www.galsys.co.uk\/news\/wp-content\/uploads\/email-time-stamp-300x188.png 300w, https:\/\/www.galsys.co.uk\/news\/wp-content\/uploads\/email-time-stamp-1024x640.png 1024w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/a><figcaption id=\"figcaption_attachment_1378\" class=\"wp-caption-text\" itemprop=\"description\"><span style=\"color: #000000;\"><strong>&#8216;Every email you send and receive has a time stamp.&#8217;<\/strong><\/span><\/figcaption><\/figure>\n<p><span style=\"color: #000000;\">Additionally, a majority of websites that you\u2019re using utilise cookies to retain your logon status.

It\u2019s not uncommon for time synchronisation of a network to be taken seriously following a security breach.<\/span><\/p>\n<p><span style=\"color: #000000;\">Networks suffering from inaccurate time issues are often relying on free, internet based, <strong><a style=\"color: #000000;\" href=\"https:\/\/www.galsys.co.uk\/network-time-servers\/\">network time servers<\/a><\/strong>. Free time servers are maintained by a third party, resulting in network administrators giving them very little attention.<\/span><\/p>\n<p><span style=\"color: #000000;\">Furthermore, free time servers are extremely vulnerable and prone to security hazards because they operate outside of a firewall. In terms of network security &amp; accurate time, free time servers are a liability rather than an asset.<\/span><\/p>\n<p><span style=\"color: #000000;\">Unless a user is in \u2018the know\u2019 about the disruption an inaccurate clock can cause, home based computers are very rarely synchronised and if they are, again, it\u2019s usually via a free internet based time server.<\/span><\/p>\n<h2><span style=\"color: #000000;\"><strong>Time synchronisation solutions<\/strong><\/span><\/h2>\n<p><span style=\"color: #000000;\">Synchronising a clock, or clocks, is very straightforward. All that is required is a dedicated network time server device.<\/span><\/p>\n<p><span style=\"color: #000000;\">For large scale computer networks, Galleon Systems\u2019 <strong><a style=\"color: #000000;\" href=\"https:\/\/www.galsys.co.uk\/ntp-servers\/nts-6001-gps-ntp-server.html\">NTS-6001-GPS NTP server<\/a><\/strong> gives you many advantages over a free time server. <\/span><\/p>\n<p><span style=\"color: #000000;\">Firstly, time is synchronised from behind a firewall, reducing the risk of hacker infiltration, whereas free time servers leave you susceptible to much publicised DDOS attacks.<\/span><\/p>\n<figure id=\"attachment_1358\" aria-describedby=\"figcaption_attachment_1358\" class=\"wp-caption aligncenter\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\" style=\"width: 340px\"><a href=\"https:\/\/www.galsys.co.uk\/news\/wp-content\/uploads\/nts-6001-1.jpg\"><img loading=\"lazy\" decoding=\"async\" itemprop=\"contentURL\" class=\"size-full wp-image-1358\" src=\"https:\/\/www.galsys.co.uk\/news\/wp-content\/uploads\/nts-6001-1.jpg\" alt=\"Time Synchronisation\" width=\"340\" height=\"210\" srcset=\"https:\/\/www.galsys.co.uk\/news\/wp-content\/uploads\/nts-6001-1.jpg 340w, https:\/\/www.galsys.co.uk\/news\/wp-content\/uploads\/nts-6001-1-300x185.jpg 300w\" sizes=\"auto, (max-width: 340px) 100vw, 340px\" \/><\/a><figcaption id=\"figcaption_attachment_1358\" class=\"wp-caption-text\" itemprop=\"description\"><span style=\"color: #000000;\"><strong>\u2018The NTS 6001 GPS NTP Server.&#8217;<\/strong><\/span><\/figcaption><\/figure>\n<p><span style=\"color: #000000;\">Secondly, it can synchronise time across thousands of your devices, accurate to the millisecond. There\u2019s minimal risk of time drift, ensuring that all your time sensitive processes are carried out on-time, every time.<\/span><\/p>\n<p><span style=\"color: #000000;\">Yes, the benefit of a free time server is that it\u2019s free; however, as a long-term solution for accurate time synchronisation they are simply inferior.<\/span><\/p>\n<p><span style=\"color: #000000;\">For the home computer, the <strong><a style=\"color: #000000;\" href=\"https:\/\/www.galsys.co.uk\/time-receivers\/ac-700-msf-time-receiver.html\">AC-700-MSF time receiver<\/a><\/strong> is the perfect companion for time synchronisation on a single PC. It operates from behind your firewall and is an easy-to-install, highly secure time server device.<\/span><\/p>\n<p><span style=\"color: #000000;\">Again, this device holds many advantages over a free time server, particularly in terms of reliability &amp; time accuracy.<\/span><\/p>\n<p><span style=\"color: #000000;\">Overall, if network security matters then accurate time synchronisation should be prioritised, especially with an increase in DDoS attacks hitting the headlines.<\/span><\/p>\n<p><span style=\"color: #000000;\">You can\u2019t put a price on network security, and while a dedicated NTP time server will require an investment, it\u2019s a long term solution for accurate time synchronisation.<\/span><\/p>\n<p><span style=\"color: #000000;\">The biggest benefit of purchasing a Galleon device is that some solutions come with an industry leading 6 year warranty &amp; all devices come with lifetime support.<\/span><\/p>\n<h2><span style=\"color: #000000;\"><strong>Order a Galleon time server now<\/strong><\/span><\/h2>\n<p><span style=\"color: #000000;\">For virtually instant time synchronisation for your computer network or home PC, get a personalised price from a Galleon representative.
