Returns the duration representation of 1 second, or the seconds from a given timestamp. Optionally, you can check it in a time zone different than yours.
How does it work in the search window?
Select Create column in the search window toolbar, then select the Second operation.
This operation can be applied with no arguments. In this case, you will get the duration representation of 1 second (duration data type, 1s).
If you add the Timestamp argument, you will get the seconds considering your current timezone. Optionally, you can specify a different time zone adding the Time zone argument to see the seconds in the specified time zone.
You can either select a column with that data type or introduce it manually.
In case you want to introduce it, note that this value should be a date: Year-Month_Day Hour:Minute:Second.Millisecond (yyyy-MM-dd HH:mm:ss.SSS) → You can skip milliseconds.
You need a valid string format the app can recognize so it returns meaningful results. You can use one of the following:
You can check the time zone codes and region names in the Configure Timezone window in Devo. Be aware that some of the codes coincide, as CST could mean Central Standard Time or China Standard Time. In that case, it would be advisable to introduce the time zone's full name. You can find them listed in the following link.
If you leave the field empty or introduce a value the app cannot recognize, it will automatically set the Time Zone argument as UTC so you will see the time in your time zone when the previous day started in UTC.
The data type of the new column values will be integer and the values shown will be 0-59.
Be aware that timestamps taking place during summer will be affected in the time zones in which they set the clock forward during summer. For example, Europe/Madrid (CET-Central European Time), which is UTC+1, becomes UTC+2 during summertime and thus timestamps in August will be affected when using that time zone. Be also aware that summertime differs between the Northern and Southern Hemispheres.
demo.ecommerce.data table, we want to create a column showing the seconds of the dates in our eventdate column. To do it, we will create a new column using the Second operation.
The arguments needed to create the new column are:
- Timestamp - eventdate column
Click Create column and you will see the following result:
How does it work in LINQ?
Use the operator
as... and add the operation syntax to create the new column. These are the valid formats for the Second operation:
second()→ Use this expression to get the representation of one second in duration data type (1s).
second(timestamp)→ Use this expression to get the seconds corresponding to the given timestamps, according to your current time zone.
second(timestamp, timezone_string)→ Use this expression to get the seconds corresponding to the given timestamps, according to the specified time zone.
You can copy the following LINQ script and try the above example on the
from demo.ecommerce.data select second(eventdate) as eventdates_seconds
