strtotime problem when clocks change

i'm using the strtotime function to convert a date and time like this:

strtotime("20-APR-2013 13:15") so that a calendar application can use it

only problem is that because this date is in the future after the clocks change, it ends up translating to 14:15 instead of 13:15. I am assuming when the clocks on the server change to match, everything will be fine, but then the problem will be that the past dates will end up being. wrong. Is there anyway around this problem?

From the manual page: [php.net...]

Each parameter of this function uses the default time zone unless a time zone is specified in that parameter. Be careful not to use different time zones in each parameter unless that is intended. See date_default_timezone_get() on the various ways to define the default time zone.

You are likely going to need to be more specific with your time string. See the Date and Time Format page for more information:

Try to do everything internally in UTC if you can. UTC is a time scale with no DST changes.

You can then convert to and from a local date/time as you need it.
