DCode™ – Timestamp Decoder

What is DCode?

DCode™ is a FREE forensic utility for converting data found on desktop and mobile devices into human-readable timestamps. It is the most comprehensive tool available for decoding timestamps and is a must-have utility for your tool box.

The software was designed to assist forensic examiners in identifying and decoding timestamp data during a forensic investigation. It will also allow the reverse process where timestamps can be encoded into a number of different formats and data types.

Encoding and Decoding Timestamp Data

DCode™ v5 now has support for 69 different timestamp formats from various operating systems and platforms. You can decode values in the form of Little-Endian Hexadecimal, Big-Endian Hexadecimal, 64-bit Integers, 32-bit Integers, Double-precision floating-point numbers and various text formats.

Time Zone Translation

DCode™ v5 also supports time zone translation and will show UTC (Zulu) times and a converted local time based on the selected time zone. If you select the “K” identifier in the timestamp pattern, DCode™ will also display the time zone designator.

When the Select Time Zone button is clicked, the following window is displayed showing a breakdown of all the parameters for each Time Zone. You can also select the No Adjustment button. This allows each timestamp to be decoded without applying any translation.

Supported Timestamp Formats

DCode™ can convert the following timestamps into a number of different input and output formats such as Numeric (Int32, Int64, Double-precision floating-point), Hexadecimal (Little-Endian), Hexadecimal (Big-Endian) and Text.

Filtering Date Ranges

To quickly identify timestamp values which may be important, DCode™ allows you to set a date range which can be used as a filter your results. To configure a date range, select Tools » Options from the menu and select a From and To Date. Once the date range has been saved, you can activate the filter by selecting Tools » Filter Date Range from the menu (or click Ctrl + R). This will filter your results and will only display values where the date falls between your selected range.
