The trigger function 'fuzzytime' description on WEB UI frontend differs from following WEB'S.
https://www.zabbix.com/documentation/2.2/manual/appendix/triggers/functions

And as I checked the source code, it is incorrect.

The following description shoud be change from 'more than' to 'less than and equal'
Timestamp not different from Zabbix server time for more than T seconds, then N = 1, 0 - otherwise
Timestamp not different from Zabbix server time for more than T seconds, then N NOT 1, 0 - otherwise

In addition, the other translations must be fixed.
