When daylight saving time is over, Pacific Standard Time (PST) is used. See Select time ranges to apply to your search and Specify time modifiers in your search.īecause event timestamps are stored in UNIX time, your searches return a consistent set of results regardless of the time zone you are in.įor example, if you search from 12:00 to 14:00 PDT (Pacific Daylight Time), that is the same as searching from 19:00 to 21:00 GMT (Greenwich Mean Time) which is 7 hours ahead of PDT. When you specify a time in your search, either by using the time range picker or using time modifiers, the time that you specify is converted into UNIX time for processing. However, for display purposes the values in the _time field are shown in a human-readable format. The values in the timestamp field in the sample data file are converted to UNIX time and stored in the _time field when the data is indexed. Let's use a set of test data that contains 35 events with various timestamps. When data is indexed and added to your Splunk instance, the Splunk indexer assumes that any timestamps in the data are in the same time zone as your Splunk instance. For example, the United Kingdom uses GMT for most of the year, but switches to British Summer Time (BST) during the summer months. However, some of the countries that use GMT switch to different time zones during their DST period. Neither GMT nor UTC ever change for Daylight Saving Time (DST).UTC is a time standard that is the basis for time and time zones worldwide.GMT is a time zone officially used in some European and African countries as their local time.However GMT is a time zone and UTC is a time standard. GMT (Greenwich Mean Time) is sometimes confused with UTC (Coordinated Universal Time). This moment in time is sometimes referred to as epoch time. UNIX time is the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), 1 January 1970. If your data does not have timestamps, the time at which your data is indexed is used as the timestamp for your events. Regardless of how time is specified in your events, timestamps are converted to UNIX time and stored in the _time field when your data is indexed. When the United States returns to Standard time, the -8 offset equates to the Pacific Standard Time (PST). San Francisco is in the Pacific timezone. The -0700 in the timestamp equates to the -7 in UTC-7.ĭuring Daylight Savings Time (DST) in the United States, the -7 offset equates to the Pacific Daylight Time (PDT). For example T11:45:30-07:00 could be expressed as UTC-7. Sometimes you might see a timestamp expressed as UTC-7 or UTC+3, which is UTC with the offset from GMT. The local time is interpreted as the same time zone as the Splunk indexer where the data is indexed. US Pacific Daylight Time, the timezone where Splunk Headquarters is located.Ī timestamp with an offset from GMT (Greenwich Mean Time)Ī timestamp expressed in UTC (Coordinated Universal Time) The timestamp might be in one of several formats, as shown in the following table: When data is indexed, the Splunk indexer looks for a timestamp in each event. The Splunk platform processes time zones when data is indexed and when data is searched.
