# SRAbsoluteTime

A value that describes when the system records the data.

## Declaration

```swift
struct SRAbsoluteTime
```

## Discussion

Discussion This value tracks monotonically increasing device-specific time, unlike mach_continuous_time, which keeps tracking across reboots. Although a fetch can query a device other than a phone (such as a paired watch), the framework consistently describes time according to the phone. Any fetch results from a paired watch are in the phone’s version of SRAbsoluteTime.
