Hey Vladimir!
MK>> ss = two digit second ranging from 00 to 59
VD> You have a little error on this field: sometimes the minute have
VD> 61 seconds - for example 31 december 2016 was 23:59:60 , or
VD> 30 june 2015 was 23:59:60 . So - this field have ranging from 00
VD> to 60 .
That is not an error since there is no guarentee that leap seconds are universally accepted. Having said that I will take the liberty of dumping the above data into coreutils-8.32 'date' and see what it thinks about it;
-={ date --date='2016-12-31 23:59:60 +0000' }=-
date: invalid date '2016-12-31 23:59:60 +0000'
-={ date --date='2015-06-30 23:59:60 +0000' }=-
date: invalid date '2015-06-30 23:59:60 +0000'
In both cases it fails. However this works for both;
-={ date --date='2016-12-31 23:59:59 +0000' }=-
Sat 31 Dec 2016 11:59:59 PM UTC
-={ date --date='2015-06-30 23:59:59 +0000' }=-

I read somewhere that leap seconds have to be added using a different method and I'll probably look it up later just in case someone makes the query. I don't recall if they (whoever they are) cited any app where you could input the datetime stamp in order to facillitate the above examples. I am fairly certain it wouldn't be found on most systems. Certainly not any FTN abandonware I am sure.
Life is good,
Maurice
