gpstime's Issues

The steps to use this gpstime file.

Hi, I want to use this gpstime to set the time of the Raspberry Pi. But the 
question is I don't how to use this file. I am sorry I am a totally new guy to 
Linux. Can you tell me how to use this file to realize the time setting step by 
step? Thank you very much. The RPI uses the Debian system. 

Please provide any additional information below.

My code doesn't see a fix on the first run - but it does the second time it's run?

Novice programmer using gpstime to set my RPi clock...
After boot and after GPS module has a valid fix, I run my python script with 
some customization of the base code. The script doesn't recognize a valid fix 
from the GPS the first time it runs. I immediately run it again and it does see 
a valid fix and it reads the time. Is there something obvious that I'm doing 
wrong? Is something getting initialized or started on the first run that 
succeeds on the second run?
Thanks for any advice,
Shawn
