![]() ![]() reltimeĬreates a field named "output" which displays stuff like "Last event was 27 seconds ago." And you don't have to do the math yourself. (If I understand what you want.) yoursearchhere So what you see may well be different from the value that is actually stored, but it will be consistent. So if you had your user timezone set to Pacific Time, then the Splunk UI will display all times (including time and now()) in Pacific Time. | eval freshness = now() - _timeĬalculates "freshness" as the number of seconds between the event timestamp and the time that the search started.įinally, you might also try the reltime command for what you want. That said - when you sign onto Splunk, there is a time zone associated with your user account. So if you had your user timezone set to Pacific Time, then the Splunk UI will display all times (including _time and now()) in Pacific Time. If youre receiving Elastic Common Schema (ECS) events in JSON format, i.e. What is the strptime-style -variable that TIMEFORMAT would use for subseconds The docs for nf suggest the strptime manpage, but being a timet (which has only second-level precision) theres no such information there. That said - when you sign onto Splunk, there is a time zone associated with your user account. This function takes a UNIX time value and renders the time as a string using the format specified. Splunk Lantern is Splunkâs customer success center that provides advice from Splunk experts on valuable data. You can find more info here: How timestamp assignment works Ive tried to used mktime and strftime, but I havent figured it out, yet. Perhaps the time zone information is not being picked up somewhere along the way, or nf needs to have a timezone setting on the indexer. The strptime function doesn't work with timestamps that consist of only a month and year. You use date and time variables to specify the format that matches string. If the data does not have the proper time, it may be because the Splunk admin who set up the forwarding missed something. strptime (, ) Takes a human readable time, represented by a string, and parses the time into a UNIX timestamp using the format you specify.So, the data is always stored in the index with _time in UTC. When the data comes from a forwarder, the forwarder (version 6.x) supplies local time zone information that Splunk uses to calculate _time in UTC. This means that for any date or time-related calculations we want to perform in our searches, we can run the strftime function against the time field in our data. Splunk uses UNIX time for the contents of the time field in events. strftime() : It is an eval function which is used to format a timestamps value Letâs say you have a timestamps field whose value is like : 1. Strftime is a Splunk search function that converts a UNIX time value to a human readable format. strptime() : It is an eval function which is used to parse a timestamps value 2. I think you have most of this from the other answers, but let me summarize: function which are used with eval command in SPLUNK : 1.
