Splunk官方文档地址:Date and time format variables
本文列出了可以在函数strftime()和strptime()中定义时间格式的变量,这些参数也可用来在事务数据中描述时间戳。
另外可以使用relative_time()和now()函数作为参数。
Variable | Description |
---|---|
%c | 采用由服务器操作系统定义的日期、时间,例如:Thu Jul 18 09:30:00 2019 for US English on Linux. |
%+ | 采用由服务器操作系统定义的日期、时间还有时区, Thu Jul 18 09:30:00 PDT 2019 for US English on Linux. |
Variable | Description |
---|---|
%Ez | Splunk-specific, timezone in minutes.Splunk特指的时区以分为单位 |
%f | 十进制微秒 |
%H | 小时(24小时制),小时数由00-23表示,前导0可接受但不是必需的 |
%I | 大写字母i。小时(12 小时制),小时数由01-12表示。前导0可接受但不是必需的。与 %p一起使用可为12小时制指定AM或PM。 |
%k | 与%H一样,小时(24 小时制)。前导0替换为空格,例如0-23。 |

%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 (or %U) | Week of the year. The %V variable starts the count at 1, which is the most common start number. The %U variable starts the count at 0. |
%w | Weekday as a decimal number. (0 = Sunday, …, 6 = Saturday) |
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. |
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. |

下表显示了使用strptime()使用多个日期时间格式变量将时间戳变为UNIX时间格式的结果。
例如,此搜索返回 UNIX 时间 1671126322.000000。
… | eval mytime=strptime(“2022-12-15T09:45:22”,“%Y-%m-%dT%H:%M:%S”)
Timestamps | Date and Time format string | UNIX time |
---|---|---|
2022-9-25T09:45:22.000 | %Y-%m-%dT%H:%M:%S.%Q | 1664124322.000000 |
2022-12-15 09:45:22 | %Y-%m-%d %H:%M:%S | 1671126322.000000 |
The following table shows the results of searches that use time variables:
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: 2021-04-13T14:00:15.000.
… | eval start=strptime(Sent, “%H:%M:%S.%N”), end=strptime(Received, “%H:%M:%S.%N”) | eval difference=end-start | table end, start, difference
Takes the values in the Sent and Received fields and converts them into a standard time using the strptime function. Then calculates the difference between the start and end times. The results are displayed in a table.
You can use the round function to round the difference to a specific number of decimal places. For example …| eval difference=round(end-start, 2).
For more information about working with dates and time, see Time modifiers for search and About searching with time in the Search Manual.
Refer to the list of tz database time zones for all permissible time zone values. For more information about how the Splunk software determines a time zone and the tz database, see Specify time zones for timestamps in Getting Data In.
Subsecond time variables such as %N and %Q can be used in metrics searches of metrics indexes that are enabled for millisecond timestamp resolution.
