Code:

ti:=(epoch MOD 84600)/3600;

...
epoch2date(1515230706) returns {2018.0106, 12.41833333}
→HMS(12.41833333) returns 12°25'06'', that two hours later, but still I must set UTC problem...

It's not a timezone problem. Take a closer look at the quoted code line. ;-)

BTW the result is UTC, so if you want local time you'll have to add 3600 s to epoch at the beginning. Just as you subtract it at the end of the opposite conversion.

BTW2: Why do you return the time as 12,4183333333 instead of 12,2506? This doesn't take more than a simple h.ms conversion.

Or, if you want to return hours, minutes and seconds separately, you may do it this way:

seconds = epoch mod 86400
hh = IP(seconds/3600)
mm = IP(seconds mod 3600)/60)
ss = seconds mod 60

Edit: Or with "iquo" as mentioned by Didier:

seconds = epoch mod 86400
hh = iquo(seconds, 3600)
mm = iquo(seconds mod 3600, 60)
ss = seconds mod 60
