![]() I recommend that everyone watch this video by Tom Scott that explains some of the problems with system time and time zones. If you move to a different time zone, you can change the setting to that time zone and events will be displayed appropriately to you. It only changes how it’s displayed to you, the user. Note: This setting doesn’t change the actual content of the event on disk. You could parse it using only stdlib: > from email. This makes it easier to see when a log event came in without needing to do any mental gymnastics to adjust the time zone to your local one. Your time string is similar to the time format in rfc 2822 (date format in email, http headers). That tells Splunk to adjust the timestamps it displays when I run a search so they’re relative to my time zone. In my case, I’m in US Eastern, so that’s what I set it to. The user should set this to the time zone they’re using Splunk from. And if your on-prem servers are set to Pacific time because they are in California, but you are accessing them from Ohio, you’ll need to set the time zone in your user preferences to Eastern time. On Splunk Cloud, for example, I’ve seen this be US Pacific time. That default means the time zone Splunk uses to display events to you will be what the search head itself is set to use. The following time variables are not supported: %c, %+, %Ez, %X, %x, %w, %s.įor example, if string X is 11:22:33, the format Y must be %Y-%m-%dT%H:%M:%S.The default setting is “- Default System Time zone -” ![]() Use this scalar function with the eval or the filter streaming functions.įunction Input timestamp: string format: string time_zone: string Function Output long If timezone is set to null, then UTC is used. This function takes three arguments: a timestamp X, a time format Y, and a timezone Z. This function parses a date string into a UNIX timestamp. | eval formatted_time=strftime(time_zone: "null", time: timestamp, format: "%H:%M:%S", ) strptime(timestamp, format, time_zone) If the timestamp field value is 1586541874588, then the value returned in the formatted_time field is 18:04:34. Returns the hour, minute, and seconds from the timestamp field in timezone UTC. Arguments Function Input time: long format: string time_zone: string Function Output long SPL2 examples The following time variables are not supported: %c, %+, %Ez, %X, %x, %w, %s. Use these common data and time format variables to specify the time-format Y that you want X to be formatted to. I discovered that Splunk Light Version 6.4.1.2 seems to have a bug where it ignores the users timezone and always reports UTC. Use the first 13 digits of a UNIX time to use the time in milliseconds. This function takes three arguments: a UNIX time X, a time-format Y, and a timezone Z, and returns X using the format specified by Y in timezone Z. This function formats a UNIX timestamp into a human-readable timestamp. | eval n=relative_time(time_zone: "GMT-0700", time: timestamp, modifier: format, time_zone) When working in the SPL View, you can write the function by using the following syntax. The following example determines the UNIX time value of the start of the hour, based on the value of timestamp, rounded down to the GMT time zone. Use this scalar function with the eval or the filter streaming functions.įunction Input time: long modifier: string time_zone: string Function Output long SPL2 examples For more information on snap-to-time and examples of relative time modifiers, see specify time modifiers in your search. If you do not want to round to a specific time zone, you can set the timezone field to null. For example, if your UNIX time corresponds to Monday 10pm PST and Tuesday 1am EST, then specifying a timezone allows you to select an accurate date that you want to round down to. This function takes three arguments: a UNIX time X, a relative time modifier Y, and a timezone Z, and returns the UNIX time value of Y applied to X rounded according to Z.īecause of the way that timezones are snapped, you must specify a timezone to determine how your time gets rounded down.
