Caché ObjectScript Reference - InterSystems Documentation

You can obtain the same current date and time information by invoking a system method, asfollows:WRITE $SYSTEM.SYS.Horolog()Refer to the “Class %SYSTEM.SYS” section of the Caché Class Reference for further details.Separating Date and TimeTo get just the date portion or just the time portion of $HOROLOG, you can use the $PIECEfunction, specifying the comma as the delimiter character:SET dateint=$PIECE($HOROLOG,",",1)SET timeint=$PIECE($HOROLOG,",",2)WRITE !,"Date and time: ",$HOROLOGWRITE !,"Date only: ",dateintWRITE !,"Time only: ",timeintTo get just the date portion of a $HOROLOG value, you can also use the following programmingtrick:SET dateint=+$HOROLOGWRITE !,"Date and time: ",$HOROLOGWRITE !,"Date only: ",dateintThe plus sign (+) causes Caché to parse the $HOROLOG string as a number. When Cachéencounters a non-numeric character (the comma) it truncates the rest of the string and returnsthe numeric portion. This is the date integer portion of the string.Date and Time ConversionsYou can use the $ZDATE function to convert the date portion of $HOROLOG into external,user-readable form. You can use the $ZTIME function to convert the time portion of$HOROLOG into external user-readable form. You can use the $ZDATETIME functionto convert both the date and time. When using $HOROLOG, setting the precision for timevalues in these functions always returns zeros as fractional seconds.You can use the $ZDATEH function to convert a user-readable date into the date portion of$HOROLOG. You can use the $ZTIMEH function to convert a user-readable time into thetime portion of $HOROLOG. You can use the $ZDATETIMEH function to convert boththe date and time to a $HOROLOG value.Setting the Date$HOROLOGYou can use the $ZUTIL(71) function to set $HOROLOG to a user-specified date for thecurrent process.Caché ObjectScript Reference 433
