toTime() function
The toTime() function converts all values in the _value column to times.
Function type: Type conversion
toTime()
Supported data types: Integer | String | Uinteger
toTime() assumes all numeric input values are nanosecond epoch timestamps.
To convert values in a column other than _value, define a custom function
patterned after the function definition,
but replace _value with your desired column.
Examples
from(bucket: "telegraf")
|> filter(fn:(r) =>
r._measurement == "mem" and
r._field == "used"
)
|> toTime()
Function definition
toTime = (tables=<-) =>
tables
|> map(fn:(r) => ({ r with _value: time(v:r._value) }))
