Comparing date/time?

Getting Started Newbie Questions
#1

Wonderful day!
 
I have to compare two different time stamps.
here is some pseudo code, that you know what I mean:

nowTime = ( os.date( "%c" ) ) write nowTime to sqlfile continueTime = nowtime +5h stop game progress if player want to continue set new nowtime, (nowTime = ( os.date( "%c" ) ) ) check if new nowtime is equal as continueTime OR later if yes continue game

Got it? I want to Compare two timestamps and when the time is reached, the game can continue.
I hope you know what I mean. How can I realise this in Lua / Corona?
Any Ideas?
 Much thanks!

  1. Why use SQL?   Better to just save this to a file as text or a JSON encoded table of field values.

  2. With basic Lua features and SSK this is easy: https://roaminggamer.github.io/RGDocs/pages/SSK2/

Here is a full example:

( Note: I’m relaunching the simulator over and over in the video.  It isn’t running in a loop on its own. )
