Re: [ferret_users]Opposite of days1900 function

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi all,
I'd just like to point out another set of functions for getting date and 
time information into different formats.  These were introduced in 
Ferret v6.0.  Given a variable on a time axis, and one or more time 
steps from that axis, these return date and time information in 
convenient forms.

yes? show func tax*
TAX_DATESTRING(A,B,C)
   Returns date string for time axis coordinate values
   A: time steps to convert
   B: variable with reference time axis
   C: output precision (STRING)

TAX_DAY(A,B)
   Returns days of month of time axis coordinate values
   A: time steps to convert
   B: variable with reference time axis

TAX_DAYFRAC(A,B)
   Returns fraction of day of time axis coordinate values
   A: time steps to convert
   B: variable with reference time axis

TAX_JDAY1900(A,B)
   Returns days since 1900 of time axis coordinate values
   A: time steps to convert
   B: variable with reference time axis

TAX_JDAY(A,B)
   Returns days of year of time axis coordinate values
   A: time steps to convert
   B: variable with reference time axis

TAX_MONTH(A,B)
   Returns months of time axis coordinate values
   A: time steps to convert
   B: variable with reference time axis

TAX_TIMES(A)
   (demonstration function) returns % good data at each time
   A: data to be checked

TAX_TSTEP(A,B)
   Returns time step values based on the new time origin
   A: variable with reference time axis
   B: desired time origin (STRING)

TAX_UNITS(A)
   Returns units of time axis coordinate values, in seconds
   A: variable with reference time axis

TAX_YEAR(A,B)
   Returns years of time axis coordinate values
   A: time steps to convert
   B: variable with reference time axis

TAX_YEARFRAC(A,B)
   Returns fraction of year of time axis coordinate values
   A: time steps to convert
   B: variable with reference time axis
