ETC/GMT time zones appear to have an incorrect adjustment sign in Empower - WKB247567

SYMPTOMS

• When we select the Node Time Zone as ETC/GMT+ in Empower Node Properties, the Node Time adjustment is reversed as ETC/GMT- time and vice versa

ENVIRONMENT

• Empower 3
• Empower 3 Personal
• Empower 3 Workgroup
• Empower 3 Enterprise

CAUSE

To conform with the POSIX style, zone names beginning with "Etc/GMT" have their sign reversed from the standard ISO 8601 convention. In the "Etc" area, zones west of GMT have a positive sign and those east have a negative sign in their name (for example, "Etc/GMT-14" is 14 hours ahead of GMT).

FIX or WORKAROUND

If you want to use the time zone with ETC/GMT option from the Time Zone List, you must use the reverse sign per your respective Time ETC/GMT time zone.

For example, if the actual time zone is ETC/GMT+3, you must select ETC/GMT-3 from the Time Zone List and vice versa.

• For now, we can advise that customers can choose to implement an ETC/GMT timezone as long they understand the importance of the +/- designation.
• The Etc/GMT time zone has never observed Daylight Savings Time and there are no future Daylight Savings Time rules for this time zone.
