cdfepoch
(Not recommended) Convert date text or serial date number to CDF formatted dates
cdfepoch is not recommended. Use
the cdflib low-level functions instead. (since R2023b) For more
information on updating your code, see Version
History.
Syntax
E = cdfepoch(date)
Description
E = cdfepoch(date) converts the specified
date to a cdfepoch object. date must be a valid
date value represented by text, as returned by datestr, or a
serial date number, returned by datenum.
date can also be a cdfepoch object. The
MATLAB®
cdfepoch object simulates the CDF_EPOCH data type
in CDF files.
Examples
Convert the current time in serial date number format to a
cdfepoch object.
% NOW function returns current time as serial date number
dateobj = cdfepoch(now)
dateobj =
cdfepoch object:
11-Mar-2009 15:09:25Convert the current time, which is returned by datestr in
text form, to a cdfepoch object.
% DATESTR function returns text representing a date
dateobj2 = cdfepoch(datestr(now))
dateobj2 =
cdfepoch object:
11-Mar-2009 15:09:25Convert the cdfepoch object to a serial date number.
dateobj = cdfepoch(now);
mydatenum = todatenum(dateobj)
mydatenum =
7.3384e+005
