In this episode Zulu time is used. Zulu time is the same world-wide and does not change based on time zones, it used by NATO and the military, especially in aviation (as do civilian pilots) so that all pilots, regardless of their location, are using the same 24-hour clock.
The external special effects shots on P2C-257 (the planet on which the Tok'ra are conducting a mission) are the same shots used in the Season 2's Need (1998). They show the entrance to a mine and a Goa'uld pyramid ship landing platform.
Carter mentioned the delay of communication to be 3 minutes due to the fact that a signal would take 3 minutes between the glider, which at that moment is close to Jupiter. However, 3 minutes would be Mars at its closest position to earth. In a best case scenario, Earth and Jupiter would be about 30 minutes away at the speed of light.
Military operations are always conducted using Zulu time (GMT); this ensures everyone is on the same time. However, there was no reason for them to be converting their times to Zulu because all of their watches were on the same time, Mountain Time. Using Zulu time was just a way to potentially add an element of error in the time because they needed to subtract 7 hours from Zulu each time in order to get Mountain Time, an unnecessarily cumbersome routine, especially for Jack, who was breathing less oxygen and might not be thinking as clearly.
All military operations are conducted using Zulu time. Especially those that involve multiple agencies that may be located anywhere around the globe.
