A comparator is simply an opamp with a certain configuation of external circuitry ( a few components) that make it function as a comparator.

Can you use the op-amp as timer?

yes, with additional circuitry. an opamp wired as a differentiator followed by an opamp wired as a comparator can provide short timing periods. an opamp wired as an integrator followed by an opamp wired as a comparator, plus some other circuits left as an exercise to the reader can provide long timing periods.


Difference between a schmitt trigger and an ordinary comparator?

A Schmitt trigger is very similar to a comparator -- both have analog input and send out either a "high" or "low" digital output. A comparator senses the difference between its "+" and "-" inputs. If the "+" input is even a little bit higher than the "-", the comparator sends out a "high". If the "-" input is even a little bit higher than the "+", the comparator sends out a "low". A comparator has only one threshold value. A Schmitt trigger can be built from a comparator and some resistors. Typically the circuit involves positive feedback -- attaching a resistor to feed a small amount of the comparator's output back to the "+" input. A Schmitt trigger has 2 threshold values.
