Definition
|
Time intervals are related short form by abbreviations. They start with a type ("Trailing", "Current", or "Most Recent"), followed by some indication of the value, and end with a unit (such as second, hour, quarter, etc.).
Interval Types:
| |
T |
Trailing |
The time of the interval right up to this instant. This interval slides through time so that it always ends at now, that is the current instant. e.g. TTM = “Trailing Twelve months” starts twelve months ago and goes up to this instant.
|
| |
C |
Current |
The current discrete interval of time. This interval describes the discrete interval we are currently in. Discrete intervals will last a predetermined amount of time and then end. Statistics kept in discrete intervals are zeroed (or reset) at the discrete transition from one interval to the next. E.g. If we are in minute two of the current five minute interval (C5m) the number reflects what’s occurred in the past 2 minutes.
|
| |
MR |
Most Recent |
The Most recent DISCRETE interval of time that has COMPLETED. So, MR5m would be the last DISCRETE five-minute interval that was COMPLETED. It is the discrete interval of time just before the CURRENT one.
