I don't think that the date command is intended for that. I can sort-of get it to work by abusing the timezone concept. Note that I had to switch signs.

stmktime
sttime(3) ShapeTools Toolkit Library sttime(3)NAME
stMktime, stWriteTime - date and time handling
SYNOPSIS
#include <config.h>
#include <sttk.h.h>
time_tstMktime (char *string);
char*stWriteTime (time_t date);
DESCRIPTION
stMktime scans the given string and tries to read a date and time from it. It understands various formats of date strings. The following is
a list of all valid formats, optional parts in brackets.
[Tue] Jan 5[,] [19]93
This includes the standard asctime(3) format.
Jan 5 With no year given, the year defaults to the current year.
[19]93/01/05 This notation requires month and day represented by exactly two digits.
5.1.[19]93 This is the usual German notation.
5.1. German notation referencing the current year.
A certain time, given together with the date must always have the following form.
hours:minutes[:seconds]
Each of the fields must be an integer value within the proper range (hours: 0-23, minutes and seconds: 0-59). Values below
10 may be written as one digit numbers.
The time value may be placed anywhere in the date string: at the beginning, at the end, or somewhere in the middle. Any amount of white-
space may be given between a field of the time value and the separating colon. The time is always considered to be local time.
stWriteTime generates a time string similar to asctime(3) from its date argument.
SEE ALSO asctime(3)BUGS
Time Zone Names within the time string (like `MET') are not handled properly. In most cases they will cause a failure.
