The Time Zone setting can be found on the Data/Trade Service Settings window, which can be accessed from the menu by selecting Global Settings >> Data/Trade Service Settings.
The Time Zone setting sets the time zone to display times in throughout Sierra Chart. The Time Zone setting offers a list of common time zones around the world. These time zones are listed by one major city that the time zone contains.
From the list of time zones, select the time zone you want to use. If the time zone you want to use is not represented in the list, you can set up a Custom Time Zone.
It is also supported to set a Different Time Zone in Individual Charts.
For troubleshooting information related to the Time Zone setting control, refer to help topic 38.
Custom Time Zones
To set a time zone that is not represented in the list, select Other/Custom DST... in the list, and press on the Set button that appears next to the list. This will display the Custom Time Zone window.
This is the abbreviated name of the time zone during standard time such as "CET" for Central European Time or "NZST" for New Zealand Standard Time. This does not show up elsewhere in the program and does not affect the time zone calculations at all, but it is necessary to have a name and useful for understanding what the custom time zone is intended to be.
This is the time offset of the time zone's local time from UTC (Coordinated Universal Time). For example, MST (Mountain Standard Time in the United States) has a UTC offset of -7, meaning the local time in MST is 7 hours earlier than UTC. This offset is without consideration to daylight savings time. Most offsets are in even hour increments, however minutes can be included as well. For example, IST (India Standard Time) has a UTC Offset of +5:30, which can be entered in the edit box as "+5:30".
Daylight Savings Time/Summer Time
A time zone may or may not use Daylight Savings Time or Summer time. If it does, additional controls are enabled to control the settings of this additional offset. An offset of +1 hour added to the UTC Offset is always used for daylight savings time.
This is the same as the Name setting above for standard time, except this one is the name of the time zone during daylight savings time, such as "CEST" for Central European Summer Time or "NZDT" for New Zealand Daylight Time.
This specifies when daylight savings time starts. The time setting is the current local time for when the change will take place. So if the time is set to 02:00:00, that means on the date of the change, the local time will go from 01:59:59 to 03:00:00.
This specifies when daylight savings time ends. The time setting is the current local time for when the change will take place. So if the time is set to 02:00:00, that means on the date of the change, the local time will go from 01:59:59 to 01:00:00.
Using Different Time Zone in Individual Charts
It is supported to use a different time zone in a chart compared to the global time zone setting in Global Settings >> Data/Trade Service Settings .
If you set a different time zone in a chart, be aware that you have done this so that you understand the timescale that you are seeing.
To set a separate time zone for a chart, select Chart >> Chart Settings >> Advanced Settings. Set the Time Zone setting to a setting other than Use Global Time Zone.
You also need to be aware that if you use a different time zone in a chart compared to the global time zone, when using the Tools >> Global Cursor On, the exact time that you see highlighted on each of the charts will be different if the time zone is different on those charts. However, the corresponding time highlighted based upon the time zone of each of the charts, will be correct.
Resolving Differences with the Transition To/From Daylight Savings Time in Different Time Zones
When the Global Time Zone setting or the chart specific Time Zone differs from the time zone the Symbol of the chart trades in and these two time zones have different rules for when transitioning to Daylight Saving Time and transitioning from Daylight Savings Time, then there will be a problem with the display of accurate times in the chart near the time where Daily Savings Time changes or when Daylight Savings Time is in effect.
The only definitive to solution to this, is that you must set either the Time Zone in the chart if you are using the chart specific Time Zone setting, or the Global Time Zone to the same time zone of the exchange where the symbol trades. Or use a Time Zone that follows the exact same Daylight Savings Time rules.
There is no other possibility to solve this kind of issue.
