Reads the current time and date from the system clock on the server that runs a remote EDMdatabase

Arguments

Type	Name	Comment
SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
EdmiPackedDate	packedDate	A variable that will receive the current time and date in an EdmiPackedDate format. Dates from January 1, 1990 to December 31, 2053 may be represented in this format.
EdmiDate	date	A variable that will receive a pointer to an EdmiDate structure containing the current time and date. See sdai.h for the declaration of EdmiDate. The data structure is a static buffer in the EDMinterface and may be overwritten by succeeding EDMinterface calls. Do not release this memory with edmfree
EdmiStringDate	stringDate	A variable that will receive a pointer to a buffer that contains the current time and date in string format. The string buffer is a static buffer in the EDMinterface and may be overwritten by succeeding EDMinterface calls. Do not release this memory with edmfree
SdaiInteger	stringFormat	Currently not used.
SdaiInvocationId	edmiInvocationId	Currently not used.

Return Value
