Differences between ESPATIME and REALNOW?
Both of them represent the actual time at the moment of their evaluation.
NOTE: When you use these variables within the free-form time criteria, an unexpected result may happen.
Example: LATEEND('%ESPATIME PLUS 15 MIN') might bring an unexpected result into the application that has been active for more than one day.
The results of the REALNOW variable will always be the same as the ESPATIME used in conjunction with the ESPADATE %ESPADATE%ESPATIME equals REALNOW but %ESPATIME equals REALNOW if it is evaluated the same day that the application was generated only.
