## 13.2 Timing

The following routines involve "time marks," used as the basis for measuring performance characteristics of the system.

`DXMarkTime() void DXMarkTimeLocal();` | Record the times of various events in system operation (e.g., the beginning and the end of module execution). Time marks are batched until `DXPrintTimes()` is called. See DXMarkTime, DXMarkTimeLocal.
`void DXPrintTimes()` | Prints time marks. The accumulation and printing of timing messages must be enabled by `DXTraceTime()`. See DXPrintTimes.
`void DXTraceTime()` | Enables or disables the accumulation of time marks. See DXTraceTime. Note: For modules linked to Data Explorer, the Trace module enables the recording and printing of times (see Chapter 1. "Data Explorer Tools" in IBM Visualization Data Explorer User's Reference).
`double DXGetTime()` | Returns the elapsed time (in seconds) since system initialization. See DXGetTime.
