= deadline = 
'''deadline''' - deadline for the task execution. 
The directive specifies, that the task has to be finished within defined period of time. 

The directive results in using the advance reservation to guarantee the requested quality of service.

* P - mandatory character,
* nY - number of years,
* nM - number of months,
* nD - number of days,
* T - time definition separator character (must be present if the values below are used)
* nH - number of hours,
* nM - number of minutes,
* nS - number of seconds.
