25. On the UFCORS Page I do not know which time zone to select. Do I have to convert to UTC (Universal Time Coordinated)?

The following timezones are supported by the User Friendly Cors Page (UFCORS):

UTC
Atlantic (New Brunswick)
Eastern Standard
Eastern Daylight Savings
Central Standard
Central Daylight Savings
Mountain Standard
Mountain Daylight Savings
Pacific Standard
Pacific Daylight Savings
Alaska
Hawaii

If you are requesting data for your time zone, the UFCORS page will automatically do the conversion to UTC for you. You do not need to do the conversion and have that represented in your start time. For example, if you want data starting at 11:00 am Eastern Standard Time, simply enter 11:00 for "Start time", and Eastern Standard Time for "Time Zone".

You must select daylight savings time if your timezone supports it and you are currently in daylight savings time. Daylight savings time begins when clocks are set from 2:00 a.m. to 3:00 a.m. on the first Sunday in April and ends when clocks are set from 3:00 a.m. to 2:00 a.m. on last Sunday in October. Hawaii, Arizona, and most of Indiana do not use daylight savings time. Remember "Spring Forward", "Fall Back".

The RINEX file times are all in UTC no matter which time zone you select on the UFCORS page.
