Hello Team,

When in calculated item a value to be returned by the timeleft() function is greater than 1.7976931348623157E+308 Zabbix returns an error on the item (The value 1.7976931348623157E+308 is too small or too large.) and sets its status to "not supported" while the correct behaviour should be that when a value is greater than 1.7976931348623157E+308 by default it should be cropped to 1.7976931348623158E+308 based on the documentation: https://www.zabbix.com/documentation/7.0/en/manual/appendix/functions/prediction
