If you have trouble reading tabs because of the timing this might 
be for you.
A tab is made up of measures.
4 quarter notes makes one measure.
8 eighth notes makes one measure
16 sixteenths makes one measure.
Each dash(—) you see is a sixteenth of a measure.
This in my opinion all tabs should be the length of a tab parts 
seen below or divided at least.
     One Measure                              Two Measures
G|————————————————|               G|————————————————|————————————————|            
D|————————————————|               D|————————————————|————————————————|
A|————————————————|            OR A|————————————————|————————————————|
E|————————————————|               E|————————————————|————————————————|


Examples of note length:
Quarter notes have about one second in between them.
  1   2   3   4   
G|0———0———0———0———|
D|————————————————|
A|————————————————|
E|————————————————|

Eighth notes read as 1 & 2 & 3 & 4 &
  1 & 2 & 3 & 4 &
G|0—0—0—0—0—0—0—0—|
D|————————————————|
A|————————————————|
E|————————————————|

Sixteenth notes read as 1 E & A 2 E & A 3 E & A 4 E & A
  1E&A2E&A3E&A4E&A
G|0000000000000000|
D|————————————————|
A|————————————————|
E|————————————————|

Same thing except spaced to make it easier on the eyes.
  1 E & A 2 E & A 3 E & A 4 E & A
G|0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0|
D|— — — — — — — — — — — — — — — —|
A|— — — — — — — — — — — — — — — —|
E|— — — — — — — — — — — — — — — —|

If a tab is longer than sixteen dashes you could just divide it 
into measures for timing
(asuming that they have the timing done right).

I know I spelled one or two words wrong. I do not have enough time 
to go back and correct them.
