Set Timecode Options

Production Start Time: Enter the production time that you want to represent in Maya. For example, if you want your Maya scene to represent a shot starting from the time code 1:32:03 of your production, enter the values 1, 32, and 3 in the hour, minute, and second fields respectively.
Frame: (Optional) Lets you specify a Production Start Time to a value that is more precise than one second.

For example, if your Production Start Time is 1 hour, 32 minutes, 3 seconds, and one half second, and the current frame rate in Maya is 30 fps, you can specify this exact Production Start Time by entering 1, 32, and 3 in the Production Start Time fields, and entering 15 in the Frame field. Entering frame 15 specifies the equivalent of one half second at the current frame rate.
Maya Start Frame: Enter the frame in your Maya scene where you want the timecode to start.
