Poetry Analysis, can someone help me?

[Felipe]

I need to do a poetry analysis, where i need to say that in my opinion, what is the meaning of the poem. the poem is Time by Allen Curnow. Can someone help me?

Here's the whole poem:

I am the nor'west air nosing among the pines
I am the water-race and the rust on railway lines
I am the mileage recorded on yellow signs.

I am dust, I am distance, I am lupins back of the beach
I am the sums sole-charge teachers teach
I am cows called to milking and the magpie's screech,

I am nine o'clock in the morning when the office is clean
I am the slap of the belting and the smell of the machine
I am the place in the park where the lovers are seen.

I am recurrent music the children hear
I am level noises in the remembering ear
I am the sawmill and the passionate second gear.

I, Time, am all these, yet these exist
Among my mountainous fabrics like a mist,
So do they the measurable world resist.

I, Time, call down, condense, confer,
On the willing memory the shapes these were:
I, more than your concious carrier,

Am island, am sea, am father, farm, and friend,
Though I am here all things my coming attend;
I am, you have heard it, the Beginning and the End.
