Specifying time zones

Because all archive records are stored using Coordinated Universal Time (UTC is a modern continuation of Greenwich Mean Time (GMT)), it is important to specify the time zone. Not specifying the time zone correctly can have undesired results. For example, if you specify 2002.11.23-12:00:00:-0000, records created in the North American Eastern Time Zone before 7 AM on November 23rd 2002 are purged.

The following table shows how to express a local time in UTC for various times zones:

Time zoneExpressed in UTC
Pacific Standard Time (PST)-0800
Mountain Standard Time (MST)-0700
Central Standard Time (CST)-0600
Eastern Standard Time (EST)-0500
Greenwich Mean Time (GMT)-0000
Central European Time (CET)+0100
Eastern European Time (EET)+0200
Emirates Time+0400
Japan Standard Time (JST)+0900

The following examples show how to delete records created before 12 AM on November 23rd 2002 according to the different time zones in which they were created:

  • For records created in Central European Time, specify:
    • 2002.11.23-12:00:00:+0100
  • For records created in United Arab Emirates, specify:
    • 2002.11.23-12:00:00:+0400
  • For records created in Japan Time, specify:
    • 2002.11.23-12:00:00:+0900
  • For records created in North American Eastern Time, specify:
    • 2002.11.23-12:00:00:-0500
