Background Information
Each language provides system variables or functions that provide the current system time. See Caché ObjectScript Reference, Caché MultiValue Basic Reference, Caché Basic Reference, and Caché SQL Reference.
In many Caché applications, dates and times are stored and transmitted in a format called $H format or $HOROLOG format. For an introduction, see Date and Time Values in the Caché Programming Orientation Guide.
