If you've been working with some of the newer releases of the products in the SAP Business Suite, you may have encountered certain applications that use the TIMESTAMP or TIMESTAMPL data types to store time-sensitive data.

#PREPROS LOG DATE AND TIME STAMP CODE#
The code excerpt in Listing 2.5 demonstrates how you can adjust the date to using offset/length semantics. For instance, you can use the offset/length functionality to initialize date or time components. In addition to typical numeric calculations, you also have the option of working with date/time fields using normal character-based semantics. Listing 2.4 Performing Time Calculations in ABAP WRITE /(60) lv_time USINGĮDIT MASK 'A minute and a half from now it will be _:_:_'. USING EDIT MASK 'The current time is _:_:_'. The code in Listing 2.4 shows how we can increment the current system time by 90 seconds using basic time arithmetic. With time calculations, the computation is based upon the seconds component of the time object. Time calculations in ABAP work very similarly to the date calculations shown in Listing 2.3. Listing 2.3 Performing Date Calculations in ABAP WRITE: / 'Future Date:', lv_date MM/DD/YYYY. In other words, you can rely on the system to ensure that you don't calculate an invalid date value (e.g., ). Here, note that the ABAP runtime environment is smart enough to roll over the date value whenever it reaches the end of a month, and so on. In terms of a date calculation in ABAP, this implies that we're increasing the day component of the date object by 30 days. Next, we increment that date value by 30. Initially, the variable lv_date is assigned the value of the current system date (e.g., the system field SY-DATUM). The code excerpt shown in Listing 2.3 demonstrates how these calculations work. Nevertheless, the ABAP runtime environment allows you to perform basic numeric operations on these types by implicitly converting them to numeric types behind the scenes. As we mentioned in Section 2.2.1, Understanding ABAP Date and Time Types, the built-in date and time types in ABAP are character types, not numeric types. When you're working with dates, you often need to perform various calculations to compute the difference between two dates, make comparisons, or determine a valid date range. Table 2.2 ABAP Date and Time Data Types 2.2.2 Date and Time Calculations The additional digits mmmuuun represent fractions of a second. TIMESTAMPL (Type P - Length 11 Decimals 7)Īn ABAP Dictionary type used to represent long timestamps in the form YYYYMMDDhhmmssmmmuuun. For example, the value 20100913102305 represents the date Septemat 10:23:05 AM. TIMESTAMP (Type P – Length 8 No decimals)Īn ABAP Dictionary type used to represent short timestamps in the form YYYYMMDDhhmmss. For example, the value 102305 represents the time 10:23:05 AM. For example, the value 20100913 represents the date September 13, 2010.Ī built-in fixed-length time type of the form HHMMSS. Data TypeĪ built-in fixed-length date type of the form YYYYMMDD. Collectively, these standards define a global time standard that can be used to convert a given time to local time, and vice versa.

UTC is roughly equivalent to the Greenwich Mean Time standard (or GMT) which refers to the mean solar time at the Royal Observatory in Greenwich, London. The term “UTC” is an abbreviation for “Consolidated Universal Time,” which is a time standard based on the International Atomic Time standard.
