FeatureLayer TimeInfo

[IsraAlhamood]

I'm currently working with a time aware layer and I need to get the timeInfo of that layer.

I'm using this method to get the time extent getTimeDefinition() and the result is undefined.

Although in the mapservice link I can find the TimeInfo section with all the details I need as below:

Time Info:

Start Time Field: WB_SPUD_DT

End Time Field: null

Track ID Field:

null

Time Extent:
[1935/01/01 00:00:00 UTC, 2016/01/01 00:00:00 UTC]
Time Reference:

N/A

Time Interval: 5

Time Interval Units: esriTimeUnitsYears

Has

Live Data: false

Export Options:
Use Time: true

Time Data Cumulative: false

Time Offset:

null

(null)

it just tells me it's undefined when I want to get it using this method. am I missing something?

please help!
