Re: Decimal seconds?

Hi Antony,

NOW is not a variable...

In the majority of cases (the exceptions are things like CUT)... 
variables are utilized by ${}

If NOW was a variable you would see it written as ${NOW}

The word NOW is actually not special.  Deep in the Asterisk source (if 
you are curious), the flow is this:


acf_strftime
  -> ast_get_timeval


"NOW" gets passed as a string to ast_get_timeval, which really scans for 
a numeric unixtime.  If the scan fails (if the input is not a proper 
seconds-since-epoch-unixtime), then it uses a default.

Oddly enough you could pass "POTATO" to STRFTIME and it would work just 
fine... since no matter what the value is, if it doesn't parse properly 
the default is ast_tvnow which is a high resolution 'now'
