# Add C source file with wrapper functions over the date/time processing functions in <time.h> system header,
# to extend the maximum year values above year 3000.
#
# Microsoft C run-time library from Visual C++ limits the year value to 3000 for x64 systems, but ASN.1
# GeneralizedTime type can use larger values
