Details:

The following transcript illustrates improper behavior of mktime.

octave> tm = gmtime(time()) ### the answer is correct!
tm =

  scalar structure containing the fields:

    usec =  117882
    sec =  53
    min =  25
    hour =  11
    mday =  22
    mon =  4
    year =  120
    wday =  5
    yday =  142
    isdst = 0
    gmtoff = 0
    zone = GMT

octave> gmtime(mktime(tm)) ## now the time has changed??
ans =

  scalar structure containing the fields:

    usec =  117882
    sec =  53
    min =  25
    hour =  8
    mday =  22
    mon =  4
    year =  120
    wday =  5
    yday =  142
    isdst = 0
    gmtoff = 0
    zone = GMT

octave> localtime(mktime(tm)) ### And this is also incorrect!!!
ans =

  scalar structure containing the fields:

    usec =  117882
    sec =  53
    min =  25
    hour =  11
    mday =  22
    mon =  4
    year =  120
    wday =  5
    yday =  142
    isdst = 0
    gmtoff =  10800
    zone = MSK
