d is a string for the number of seconds in Lilian format. The value for d must have a computational type and is converted to FLOAT BINARY(53) if necessary.
p is a supported date/time pattern. If not specified, SECSTODATE uses the value YYYYMMDDHHMISS9999, which is the same format returned by DATETIME.
w specifies an expression (such as 1976) that can be converted to an integer.
Description
Returns a non-varying character string containing the date in a pattern p that corresponds to d seconds in Lilian format.
See the help topic Date/Time Built-in Functions for more information about Lilian format and supported date/time patterns.
