How do you setup daylight savings for all products?
US Time Zones:
Pacific: PST+8PDT+7,M3.2.0,M11.1.0
Mountain: MST+7MDT+6,M3.2.0,M11.1.0
Central: CST+6CDT+5,M3.2.0,M11.1.0
Eastern: EST+5EDT+4,M3.2.0,M11.1.0
Note: For GXP2200 that doesn't have self-defined time zone option, please select the matching time zone under time zone selection list.
Pacific Example:
Time Zone
Since US is west of the Prime Meridian, it will use “+” positive for the offset. Pacific Standard Time (PST) offset is UTC -8:00, so you will change that to PST+8. If you look up PST day light savings, you will find out that it will change to Pacific Daylight Time (PDT) and will move one hour forward (Fall/Autumn BACK, Spring FORWARD). The PDT offset is UTC -7:00, so you will use PDT+7. Daylight Savings
Before we continue, make sure to add a “,” comma. The rest of the syntax is adding the dates where daylight savings takes place. First section is for when daylight savings starts. Second section is for daylight savings ends. “M” is for month and “3” is March, 3rd month of the year. The next number is for the number of the week which is “2”, the second week of the Month. Last number is “0” which stands for the first day of the week which is Sunday. Sunday =0,Monday=1, Tuesday =2, etc. Add another comma “,” to separate between starting and ending daylight savings. Daylight savings ending starts with “M11” which is November, followed by “1” (first week) and “0” (Sunday). If you look up daylight savings US, you’ll find out that it starts on March 10th, (3rd month, 2nd week on Sunday = M3.2.0) and ends on November 3rd (11th month, 1st week on Sunday = M11.1.0).
