"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:

curl_getdate
curl_getdate(3) libcurl Manual curl_getdate(3)NAME
curl_getdate - Convert a date string to number of seconds
SYNOPSIS
#include <curl/curl.h>
time_t curl_getdate(char *datestring, time_t *now );
DESCRIPTION curl_getdate(3) returns the number of seconds since the Epoch, January 1st 1970 00:00:00 in the UTC time zone, for the date and time that
the datestring parameter specifies. The now parameter is not used, pass a NULL there.
PARSING DATES AND TIMES
A "date" is a string containing several items separated by whitespace. The order of the items is immaterial. A date string may contain
many flavors of items:
calendar date items
Can be specified several ways. Month names can only be three-letter english abbreviations, numbers can be zero-prefixed and the
year may use 2 or 4 digits. Examples: 06 Nov 1994, 06-Nov-94 and Nov-94 6.
time of the day items
This string specifies the time on a given day. You must specify it with 6 digits with two colons: HH:MM:SS. To not include the time
in a date string, will make the function assume 00:00:00. Example: 18:19:21.
time zone items
Specifies international time zone. There are a few acronyms supported, but in general you should instead use the specific relative
time compared to UTC. Supported formats include: -1200, MST, +0100.
day of the week items
Specifies a day of the week. Days of the week may be spelled out in full (using english): `Sunday', `Monday', etc or they may be
abbreviated to their first three letters. This is usually not info that adds anything.
pure numbers
If a decimal number of the form YYYYMMDD appears, then YYYY is read as the year, MM as the month number and DD as the day of the
month, for the specified calendar date.

STANDARDS
This parser was written to handle date formats specified in RFC 822 (including the update in RFC 1123) using time zone name or time zone
delta and RFC 850 (obsoleted by RFC 1036) and ANSI C's asctime() format. These formats are the only ones RFC 7231 says HTTP applications
may use.
RETURN VALUE
This function returns -1 when it fails to parse the date string. Otherwise it returns the number of seconds as described.
If the year is larger than 2037 on systems with 32 bit time_t, this function will return 0x7fffffff (since that is the largest possible
signed 32 bit number).
Having a 64 bit time_t is not a guarantee that dates beyond 03:14:07 UTC, January 19, 2038 will work fine. On systems with a 64 bit time_t
but with a crippled mktime(), curl_getdate(3) will return -1 in this case.
