time    10 09    timestamp   strtotime  time    timestamp one hour later    timestamp   3600     3600 sec    1 hour     Formats the timestamp to HH MM   gt  outputs 11 09  echo strftime   H  M    timestamp one hour later      As crolpa suggested  you can also do    echo date  H i    timestamp one hour later     Check PHP manual for strtotime    strftime   and date   for details   BTW  in your initial code  you need to add some quotes otherwise you will get PHP syntax errors    time   10 09     wrong syntax  time    10 09      syntax OK   time   date H i  strtotime   1 hour        wrong syntax  time   date  H i   strtotime   1 hour        syntax OK

Worked for me     timestamp   strtotime  10 09     60 60    time   date  H i    timestamp    echo  time   11 09     Explanation   strtotime  10 09   creates a numerical timestamp in seconds  something like 1510450372  Simply add or remove the amount of seconds you need and use date   to convert it back into a human readable format    timestamp   strtotime  10 09     60 60     10 09   1 hour  timestamp   strtotime  10 09     60 60 2     10 09   2 hours  timestamp   strtotime  10 09   - 60 60     10 09 - 1 hour   time   also creates a numerical timestamp but for right now  You can use it in the same way    timestamp   time     60 60     now   1 hour

Beware of adding 3600   may be a problem on day change because of unix timestamp format uses moth before day   e g  2012-03-02 23 33 33 would become 2014-01-13 13 00 00 by adding 3600 better use mktime and date functions they can handle this and things like adding 25 hours etc
