%AddIntervalMono function

Function

The function adds relative time TimeR to absolute time TimeA. A result is value of Absolute time type.

Declaration

TIME %AddIntervalMono(
   TIME in TimeA,
   REAL in TimeR,
 )

Parameters

TimeA	Absolute time.
TimeR	Relative time.

Description

The function %AddIntervalMono adds relative time to absolute one. The result will be influenced by the fact that the time jump (between summer and winter time) was or was not performed in this interval. E.g., if 3 hours are added to 1:00 a.m., the result can be 3:00 (jump to winter-time), 4:00 or 5:00 a.m. (jump to summer-time) in Slovakia.
