No, it's not the same.
While many Christian preachers are expecting Jesus to return any minute now, they are not out there instructing their followers to kill all non-believers in order to speed things along.
The typical POV of Christians who believe these are the Last Days is to expect the be among the truly faithful who are "raptured" up off the face of the Earth before the AntiChrist takes power.
Those Christians who are currently "lukewarm" (so the theory goes) will not be "raptured," but will become serious in their faith when they see their fellows vanish before their eyes. These "left behind" Christians will be the ones who suffer persecution under the AntiChrist, and who will fight the AntiChrist in Armageddon.
Overall, the Christian End-Times belief system is a reactive one. And the most serious believers do not even expect to be here for the real fight. And the fight will not begin until Jesus Himself returns to lead His followers.
In contrast. the typical Muslim End-Times belief system is a proactive one. They see it as a duty to wage jihad against any infidels as time winds down. And with the new allegorical interpretation, they do not even need to wait for an individual Mahdi, for all jihadists might collectively be the Mahdi. But even if there will be one individual Mahdi, there is no need to wait for his lead.
For instance, “when a brother in the east can speak to a brother in the west” is one “Sign of Qiyama.” So the radio, telephone, e-mail, etc. “proves” that the final jihad is immanent.
I seem to recall this as being one of the reasons for the ulama taking on Abd al Aziz over the use of radio in 1920's. That episode points out two interesting features - even very conservative religious figures will change their minds quickly if they think it's in the interest of a strict intepretation of the Koran to do so (Abd al Aziz pointed out that readings from the Koran could be broadcast) but that tendency works both ways (the ulama had supported Abd al Aziz against the Ikhwan a bit earlier).
