+Subject: [PATCH] 32bit xclaim fix (#1444)
+
+This should fix the XCLAIM issue on 32-bit PHP installs.
+
+This change will allow the user to pass the XCLAIM TIME option pretty much any way they want (string, long, or float) and it should work. Note that in 32-bit PHP they will only be able to pass exact values <= 2^53 as PHP will use a double precision floating point for integer overflows.
