Because of the different time zones, it is important for GTX users to setup their Local Time so that no confusion arises as to the actual start time of races occurring in a time zone different to their own.

The diagram below shows examples of three races in different time zones, one each at Cheltenham, Caulfield and Belmont Park. It also demonstrates the start times of those three races expressed as a local time in each of four time zones, where the GTX users in each of those zones have set their Local Time correctly.

Take the Caulfield race for example. In the eastern states of Australia, the race starts at 12.00 midday and the Race Details Header in GTX signifies that start time.  To a South Australian, that same race starts at 11.30am local time, and if the GTX user's Local Time settings are correct, the Race Details Header will display the Caulfield start time expressed in South Australian time.

Setup Local Time

To set up your local time, start by clicking 'Setup' on the GTX Menu bar, then click 'Local Time'. The 'Local Time is...' box opens, showing a number of text boxes that display the number of minutes difference between various time zones.

You have two options for adjusting your local time - automatic or manual. Please note that some earlier versions of Windows 10 did not allow the Auto button to operate correctly. See Auto adjustment below.

Manual adjustment

If you know the time variations between time zones in Australia, you can manually adjust each setting by placing your mouse pointer on the setting you want to change and clicking with the left mouse button to increase the minutes, or with the right mouse button to decrease the minutes. Each click changes the setting by five minutes. Holding down each button will result in a rapid increase or decrease. manual adjustment

The diagram below shows the 'Local time is...' box showing the correct settings for the east coast and South Australia and West Australia. Please note these are for Standard time, not Daylight Saving time.

You will need to adjust your settings again after the twice yearly changes, in some states, from Standard time to Daylight Saving time and back again.

It’s a simple matter to have GTX adjust the times to your local time – just click on the Auto button. However this will work only if your Windows® Time Zone properties are correct. However, some earlier versions of Windows 10 did not allow the Auto button to operate correctly, so it would be wise to check your time offsets with the above diagrams after using Auto if you are using an earlier version of Windows 10.

Time Zones

Successful operation of GTX resulting from both the above adjustment methods require that your computer's clock and the time zone are set correctly.

This is usually originally set during the installation of the Windows® operating system and is easy to check. To set your time and time zone in Windows 10, go to Start > Settings > Time & language > Date & time.

In the Time Zone section you will see the currently selected time zone which should be your local time zone. If it isn't, click on the down arrow which will display the time zones list where you can select your appropriate zone.

The alternate and much simpler method is to simply click the Set PC clock button, while you are connected to the Internet. GTX will connect to an Internet Time Server and set your computer's clock to the correct time.

Settings will need to be readjusted after the twice yearly changes in some states, from Standard time to Daylight Saving time and back again. The Auto button will facilitate this adjustment but will work only if you allow Windows® to adjust your computer's clock at the appropriate times, with the setting below, or you adjust the clock manually.

Please note: After changes to Local Time, close and restart GTX to allow the new times to be read into memory.
