Welcome to another exciting journey into the world of AL programming! Today, we'll demystify the enigma behind Unix timestamps and learn how to seamlessly convert between these number-heavy representations and the more friendly date and time formats we're familiar with.
Imagine being handed a number — 1696867491. Looks confusing, right? But did you know that this is actually a timestamp representing a specific moment in time? That's the beauty of Unix timestamps: their ability to capture moments as simple integers. And with AL, converting these cryptic numbers to human-friendly dates becomes a walk in the park!
Let's dive into our UnixTimestampToDate procedure:
procedure UnixTimestampToDate(DateInMs: BigInteger): Date var TypeHelper: Codeunit "Type Helper"; begin exit(DT2Date(TypeHelper.EvaluateUnixTimestamp(DateInMs))); end;
This snippet effortlessly takes a Unix timestamp in milliseconds and, with the help of our trusty Type Helper, translates it into a format more pleasing to our eyes—a classic date.
On the flip side, have you ever wondered how to send a date into the vast universe of Unix numbers? Our next hero, DateTimeToUnixTimestamp, does just that:
procedure DateTimeToUnixTimestamp(DateTimeValue: DateTime): BigInteger var EpochDateTime: DateTime; begin // Calculate the Unix timestamp based on the Epoch datetime of 1/1/1970 EpochDateTime := CreateDateTime(DMY2Date(1, 1, 1970), 0T); exit((DateTimeValue - EpochDateTime) / 1000); end;
By referencing the "starting point" of Unix time (the Epoch: midnight of January 1, 1970), this procedure efficiently calculates the seconds that have elapsed since, producing our desired Unix timestamp.
In essence, Unix timestamps and human-friendly dates are two sides of the same coin. And with AL, moving between these two realms has never been easier. So, the next time you come across a seemingly random number in your database or API calls, remember: there's a moment in time hidden inside, just waiting to be revealed! 📅🕰️
Stay tuned for more AL adventures, and happy coding!
