## timeinsts

timeinsts — Read absolute time in seconds.

## Description

Read absolute time, in seconds, since the start of an instance of an instrument.

## Syntax

    kres timeinsts

## Performance

Time in seconds is available with timeinsts. This would return 0.5 after half a second.

timeinsts produces a k-rate variable for output. There are no input parameters.

timeinsts is similar to times except it returns the time since the start of this instance of the instrument.

## Examples

Here is an example of the timeinsts opcode. It uses the file timeinsts.csd.

Example 931. Example of the timeinsts opcode.
