Inconsistent comment for SetTimer in TimerManager does not specify that InRate and InFirstDelay should be in seconds

The comments for SetTimer in TimerManager.h do not specify that the time is in seconds. This is a discrepancy from comments for Blueprint Set Timer nodes, which do specify that the time is in seconds.

1. Open KismetSystemLibrary.h.
2. Locate the K2_SetTimer function declaration.
3. Note that the comment for the Time parameter indicates it is in seconds.
4. Open TimerManager.h.
5. Locate the SetTimer template.

RESULT:
The comment for InRate does not specify that the time is in seconds, as opposed to milliseconds.

EXPECTED:
The comment matches the comment for Blueprint nodes in specifying that the delay time is in seconds.
