+\subsection{ASN.1 GeneralizedTime}
+
+The GeneralizedTime type is to store a date and time in ASN.1 format.  It uses the following structure to organize the time.
+
+\index{ltc\_utctime structure}
+\begin{verbatim}
+typedef struct {
+   unsigned YYYY, /* year              0--9999 */
+            MM, /* month               1--12 */
+            DD, /* day                 1--31 */
+            hh, /* hour                0--23 */
+            mm, /* minute              0--59 */
+            ss, /* second              0--59 */
+            fs, /* fractional seconds  1--UINT_MAX */
+            off_dir, /* timezone offset direction 0 == +, 1 == - */
+            off_hh, /* timezone offset hours */
+            off_mm; /* timezone offset minutes */
+} ltc_generalizedtime;
+\end{verbatim}
+
+The time can be offset plus or minus a set amount of hours (off\_hh) and minutes (off\_mm).  When \textit{off\_dir} is zero, the time will be added otherwise it
+will be subtracted.  For instance, the array $\lbrace 2005, 6, 20, 22, 4, 0, 122, 0, 5, 0 \rbrace$ represents the current time of
+\textit{2005, June 20th, 22:04:00.122} with a time offset of +05h00.

+\end{verbatim}
+
+The encoder will store time in one of the following ASN.1 formats, either \textit{YYYYMMDDhhmmssZ} or
+\textit{YYYYMMDDhhmmss$\pm$hhmm} or\textit{YYYYMMDDhhmmss.fsZ} or \textit{YYYYMMDDhhmmss.fs$\pm$hhmm},
+and perform minimal error checking on the input.
+The decoder will read all valid ASN.1 formats and perform range checking on the values (not complete but
+rational) useful for catching packet errors.
+
+The fractional seconds are always added in case they are not $0$.
+The implementation of fractional seconds is currently unreliable and you can't detect decoded
+resp. encode leading $0$'s (e.g. \textit{20170424232717.005Z} would be decoded as
+\textit{22. April 2017, 23:27:17.5}).
+
+It is suggested that decoded data be further scrutinized (e.g. days of month in particular).

 \subsection{ASN.1 CHOICE}
 
 The CHOICE ASN.1 type represents a union of ASN.1 types all of which are stored in a \textit{ltc\_asn1\_list}.  There is no encoder for the CHOICE type, only a
