Hi,

I have a matlab variable as serial date (class double) in the form
'dd-mmm-yyyy HH:MM:SS'.

format long
disp( tx(40:60,1) )

1.0e+05 *

   7.356000000813091
   7.356000000956856
   7.356000001305921
   7.356000001654985
   7.356000002004049
   7.356000002353113
   7.356000002702178
   7.356000003397179
   7.356000004092182
   7.356000004787183
   7.356000005482185
   7.356000006177187
   7.356000006940080
   7.356000007702975
   7.356000008465869
   7.356000009228763
   7.356000009991657
   7.356000010754551
   7.356000011517445
   7.356000012280339
   7.356000013085329

It should be the same as

datestr( tx(40:60,1), 0)

01-Jan-2014 00:00:07
01-Jan-2014 00:00:08
01-Jan-2014 00:00:11
01-Jan-2014 00:00:14
01-Jan-2014 00:00:17
01-Jan-2014 00:00:20
01-Jan-2014 00:00:23
01-Jan-2014 00:00:29
01-Jan-2014 00:00:35
01-Jan-2014 00:00:41
01-Jan-2014 00:00:47
01-Jan-2014 00:00:53
01-Jan-2014 00:00:59
01-Jan-2014 00:01:06
01-Jan-2014 00:01:13
01-Jan-2014 00:01:19
01-Jan-2014 00:01:26
01-Jan-2014 00:01:32
01-Jan-2014 00:01:39
01-Jan-2014 00:01:46
01-Jan-2014 00:01:53

I can easily convert it with Matlab but then I will obtain a character
format which is useless. I can also make use of cellstr(datestr(tx(:,1),
0)) but then I can't save it in ASCII file.

The origin of the Matlab format is supposed to be "0000-00-00". This is the
only origin which results in "2014-01-01" which is my actual start date.

Can somebody please tell me how I can simply convert serial datetime to
datetime in R.

Thanks in advance.

All the best,

Christoph
