"date -d" is not supported in the version I am using
You don't need date -d for this type of things - use the TZ-variable (Time Zone) instead.
You see, time ist stored in "UTC" (universal time coordinated) in UNIX systems. the local time is just an offset from this, and this offset is set by the TZ variable, which you can change for a single command, for instance:
You see, adding/subtracting 24 to the TZ variable changes the output by 24 hours - which is a day. The same way you can get any arbitrary date, even in the future:

DATE(1) General Commands Manual DATE(1)NAME
date - print and set the date
SYNOPSIS
date [-nu] [-d dst] [-t timezone] [yymmddhhmm [.ss] ]
DESCRIPTION
If no arguments are given, the current date and time are printed. Providing an argument will set the desired date; only the superuser can
set the date. The -d and -t flags set the kernel's values for daylight savings time and minutes west of GMT. If dst is non-zero, future
calls to gettimeofday(2) will return a non-zero tz_dsttime. Timezone provides the number of minutes returned by future calls to gettimeof-
day(2) in tz_minuteswest. The -u flag is used to display or set the date in GMT (universal) time. yy represents the last two digits of
the year; the first mm is the month number; dd is the day number; hh is the hour number (24 hour system); the second mm is the minute num-
ber; .ss is optional and represents the seconds. For example:
date 8506131627
sets the date to June 13 1985, 4:27 PM. The year, month and day may be omitted; the default values will be the current ones. The system
operates in GMT. Date takes care of the conversion to and from local standard and daylight-saving time.
If timed(8) is running to synchronize the clocks of machines in a local area network, date sets the time globally on all those machines
unless the -n option is given.
FILES
/usr/adm/wtmp to record time-setting. In /usr/adm/messages, date records the name of the user setting the time.

TSP: The Time Synchronization Protocol for UNIX 4.3BSD, R. Gusella and S. Zatti
DIAGNOSTICS
Exit status is 0 on success, 1 on complete failure to set the date, and 2 on successfully setting the local date but failing globally.
Occasionally, when timed synchronizes the time on many hosts, the setting of a new time value may require more than a few seconds. On
these occasions, date prints: `Network time being set'. The message `Communication error with timed' occurs when the communication between
date and timed fails.
BUGS
The system attempts to keep the date in a format closely compatible with VMS. VMS, however, uses local time (rather than GMT) and does not
understand daylight-saving time. Thus, if you use both UNIX and VMS, VMS will be running on GMT.
