you could create one simple timer just like that...

pawn Код:

new jobTime[MAX_PLAYERS];

pawn Код:

public OnGameModeInit()
{
  SetTimer("UpdateJob", 60000, 1);
  return 1;
}

pawn Код:

forward UpdateJob();
public UpdateJob()
{
  for(new i; i < MAX_PLAYERS; i++) if(IsPlayerConnected(i))
  {
    if(jobTime[i] > 0) jobTime[i]--;
  }
}

pawn Код:

//When a player finishes his job set jobTime to whatever you want
jobTime[playerid] = 30; // Next job available in 30 minutes

new str[128];

if(jobTime[playerid] > 0)
{
  format(str, sizeof(str), "Please come back in %d minutes...", jobTime[playerid]);
  SendClientMessage(playerid, WHITE);
}
