Set the lower bound on the 100 year range
None.
VARIABLE I/O DESCRIPTION -------- --- -------------------------------------------------- year I Lower bound on the 100 year interval of expansion
year is the year associated with the lower bound on all
year expansions computed by texpyr_. For example
if year is 1980, then the range of years that
can be abbreviated is from 1980 to 2079.
None.
None.
This routine allows all of the SPICE time subsystem to handle
uniformly the expansion of "abbreviated" years. (i.e. the
remainder after dividing the actual year by 100). The input
supplied to this routine represents the lower bound of the
expansion interval. The upper bound of the expansion interval
is year + 99.
The default expansion interval is from 1969 to 2068.
The default behavior is as follows
year input year Output
---------- -----------
00 2000
01 2001

Suppose that you need to manipulate time strings and that
you want to treat years components in the range from 0 to 99
as being abbreviations for years in the range from
1980 to 2079 (provided that the years are not modified by
an ERA substring). The code fragment below shows how you
could go about this.
Early in your application set up the lower bound for the
expansion of abbreviated years.
tsetyr_c ( 1980 );
