Setting date & time of voicemail message

Hi, I have a recorded greeting that I want to put in new voicemail boxes as an introduction to how to use the voicemail system.

The greeting is recorded, and I place it in the INBOX of the proper folder, but I’d like to set the date and time of the greeting to when the person’s extension was created.

The date and time is taken from the MSG00??.txt file from a parameter called origtime, but what is the routine to update that number?

The format of the number is:

origdate=Wed Sep 12 08:36:37 PM CDT 2007
origtime=1189647397

Is there a utility I can use to calculate the number based on the current date and time? Has anyone done something similar? Thanks.
