 We all know that Sudan will change its timezone from GMT+3  to GMT+2

 so I'm curious about the effect of this change on services,
 transactions,  SSLs  licences, DB. .. etc?
 specially the services with timestamps :/
 Also what will be the impact of this change on  ISPs ?

As Patrick pointed out: if you're running your servers and
infrastructure on UTC (which you really, really, really should be
doing), you should not have any serious problems.  Time will continue to
move monotonically forward.  Anything that converts your UTC timestamps
to local time will need to be aware of the new timezone though.

You should make sure that anything which cares about timezones has the
updated timezone data (2017c of tzinfo) installed:

This hasn't landed in FreeBSD yet, but it will soon (people have been
prodded and worst case I can do it).  Other operating systems will
probably update soon too.

Stopping all services for an hour is probably overreacting but it might
be wise to do a sanity-check of billing systems in particular.  If
they're running on local time, you will need to figure out what happens
when time moves backwards.  If the hour between 02:00 and 03:00 local
time happens twice, you may want to point this out to your customers.
