Using time variables

You can use variables in several different ways:

There are variables that produce dates, variables that produce times, and variables that produce both dates and times.

Date and time variables

The following table lists variables that produce both a date and a time.

Variable Description
%c The date and time in the current locale's format as defined by the server's operating system. For example, Thu Jul 18 09:30:00 2019 for US English on Linux.
%+ The date and time with time zone in the current locale's format as defined by the server's operating system. For example, Thu Jul 18 09:30:00 PDT 2019 for US English on Linux.

Time variables

The following table lists variables that produce a time.

Variable Description
%Ez Splunk-specific, timezone in minutes.
%H Hour (24-hour clock) as a decimal number. Hours are represented by the values 00 to 23. Leading zeros are accepted but not required.
%I Hour (12-hour clock) with the hours represented by the values 01 to 12. Leading zeros are accepted but not required.
%k Like %H, the hour (24-hour clock) as a decimal number. Leading zeros are replaced by a space, for example 0 to 23.
%M Minute as a decimal number. Minutes are represented by the values 00 to 59. Leading zeros are accepted but not required.
%N The number of subsecond digits. The default is %9N. You can specify %3N = milliseconds, %6N = microseconds, %9N = nanoseconds.
%p AM or PM.
%Q The subsecond component of a UTC timestamp. The default is milliseconds, %3Q. Valid values are:
  •  %3Q = milliseconds, with values of 000-999
  •  %6Q = microseconds, with values of 000000-999999
  •  %9Q = nanoseconds, with values of 000000000-999999999
%S Second as a decimal number, for example 00 to 59.
%s The Unix Epoch Time timestamp, or the number of seconds since the Epoch: 1970-01-01 00:00:00 +0000 (UTC). (1484993700 is Tue Jan 21 10:15:00 2020)
%T The time in 24-hour notation (%H:%M:%S). For example 23:59:59.
%X The time in the format for the current locale. For US English the format for 9:30 AM is 9:30:00.
%Z The timezone abbreviation. For example EST for US Eastern Standard Time.
%z The timezone offset from UTC, in hour and minute: +hhmm or -hhmm. For example, for 5 hours before UTC the values is -0500 which is US Eastern Standard Time.

Examples:

  • Use %z to specify hour and minute, for example -0500
  • Use %:z to specify hour and minute separated by a colon, for example -5:00
  • Use %::z to specify hour minute and second separated with colons, for example -05:00:00
  • Use %:::z to specify hour only, for example -05
%% A literal "%" character.

Date variables

The following table lists variables that produce a date.

Variable Description
%F Equivalent to %Y-%m-%d (the ISO 8601 date format).
%x The date in the format of the current locale. For example, 7/13/2019 for US English.

Specifying days and weeks

The following table lists variables that produce values for days and weeks.

Variable Description
%A Full weekday name. (Sunday, ..., Saturday)
%a Abbreviated weekday name. (Sun, ... ,Sat)
%d Day of the month as a decimal number, includes a leading zero. (01 to 31)
%e Like %d, the day of the month as a decimal number, but a leading zero is replaced by a space. (1 to 31)
%j Day of year as a decimal number, includes a leading zero. (001 to 366)
%V Week of the year. (1 to 52)
%w Weekday as a decimal number. (0 = Sunday, ..., 6 = Saturday)

Specifying months

The following table lists variables that produce values for months.

Variable Description
%b Abbreviated month name. (Jan, Feb, etc.)
%B Full month name. (January, February, etc.)
%m Month as a decimal number. (01 to 12). Leading zeros are accepted but not required.

Specifying year

The following table lists variables that produce values for years.

Variable Description
%y Year as a decimal number, without the century. (00 to 99). Leading zeros are accepted but not required.
%Y Year as a decimal number with century. For example, 2020.

Examples

The following table shows the results of some time format strings:

Time format string Result
%Y-%m-%d 2019-12-31
%y-%m-%d 19-12-31
%b %d, %Y Feb 11, 2020
%d%b '%y = %Y-%m-%d 23 Apr '20 = 2020-04-23

The following table shows the results of searches that use time variables:

Sample search Result

host="www1" | eval WeekNo = strftime(_time, "%V")

Creates a field called WeekNo and returns the values for the week numbers that correspond to the dates in the _time field.

... | eval mytime=strftime(_time,"%Y-%m-%dT%H:%M:%S.%Q")

Creates a field called mytime and returns the converted timestamp values in the _time field. The values are stored in UNIX format and converted using the format specified, which is the ISO 8601 format. For example: 2020-04-13T14:00:15.000.
