Hi,
what about,
dl = {DatePlus[#], RandomInteger[{1, 40}]} & /@ (Range[12]*-1)
Manipulate[DateListPlot[dl, Joined -> True],
Dynamic[{DateList[First@p1],
Last@p1}], {{p1, {AbsoluteTime[dl[[4, 1]]], dl[[4, 2]]}}, Locator}]
and reading the documentation of DateList, AbsoluteTime, ... and maybe
the "Date and Time Functions" tutorial (tutorial/DateAndTimeFunctions)?
Cheers
Patrick
