NOTE: We've guessed that you're not using a client that supports colored tables and have tried to compensate. Low graphics mode looks much better on clients that do... we recommend switching to Netscape 3.0 or Microsoft Internet Explorer.

Converting from AM/PM to UTC
for both standard and daylight saving time


Standard Time:
When converting to Coordinated Universal Time (UTC), the local AM/PM time must be converted to a 24-hour clock. Then, use the chart below to convert to UTC.

From Local Time to UTC:
Eastern Standard Time (EST) EST + 5 hours = UTC
Central Standard Time (CST) CST + 6 hours = UTC
Mountain Standard Time (MST) MST + 7 hours = UTC
Pacific Standard Time (PST) PST + 8 hours = UTC

Some Examples:

If the UTC time is greater than 2359, then you have crossed over to the next day. So for example, 2430 becomes 0030 the day after.

Daylight Saving Time:
When converting from Daylight Saving Time to UTC, the conversions are similar but the UTC Time is one hour less than when converting than its Standard Time counterpart. Local AM/PM time must be converted to a 24-hour clock. Then, use the chart below to convert to UTC.

From Local Daylight Saving Time to UTC:
Eastern Daylight Time (EDT) EDT + 4 hours = UTC
Central Daylight Time (CDT) CDT + 5 hours = UTC
Mountain Daylight Time (MDT) MDT + 6 hours = UTC
Pacific Daylight Time (PDT) PDT + 7 hours = UTC
