You can use gmmktime function without arguments to obtain the current UTC timestamp    time   gmmktime    echo date  Y-m-d H i s    time      gmmktime will only work if your server time is using UTC  For example  my server is set to US Pacific  the listed function above echos back Pacific time

Other than calling gmdate you can also put this code before your rest of the code    lt  php date default timezone set  UTC      gt    That will make rest of your date time related calls to use GMT UTC timezone

with string GMT UTC   -0400 or GMT UTC   -1000 based on local timings   Your custom format is just missing O to give you the timezone offsets from local time      Difference to Greenwich time  GMT  in hours   Example   0200   date default timezone set  America La Paz    echo date  Y-m-d H i s O         2018-01-12 12 10 11 -0400   However  for maximized portability interoperability  I would recommend using the ISO8601 date format c  date default timezone set  America La Paz    echo date  c         2018-01-12T12 10 11-04 00   date default timezone set  Australia Brisbane    echo date  c         2018-01-13T02 10 11 10 00   You can use also gmdate and the timezone offset string will always be  00 00  date default timezone set  America La Paz    echo gmdate  c         2018-01-12T16 10 11 00 00   date default timezone set  Australia Brisbane    echo gmdate  c         2018-01-12T16 10 11 00 00
