How to Convert Time into Your Local Time Using UTC Hour Offset Numbers

  1. Convert the 24-hour time format to 12-hour time format if your local time uses the 12-hour format. To make the conversion, follow these steps: If the offset-adjusted time is between 12:01 and 23:59, inclusive, subtract 12 from the adjusted time, and then append P.M.
  2. The AssumeUniversal flag tells the parser that the date/time is already UTC; the combination of AssumeUniversal and AdjustToUniversal tells it not to convert the result to 'local' time, which it will try to do by default. (I personally try to deal exclusively with UTC in the business / application / service layer(s) anyway.

Time and dates, especailly server time stamps, are sometimes written with strange + and – signs next to a UTC abbreviation. Well, the UTC stands for Coordinated Universal Time, the time standard of the 25 worldwide time zones.

These numbers are not there to confuse you, they are there to help. Using these numbers, which are called UTC Offset numbers, you can convert any time to your local time. You can essentially figure out what time it is in your time zone, just by using these handy offsets.

Steps to Convert Local Time from UTC Offsets

Take these simple steps to change any time into your local time using the UTC offset.

  1. Find your local time zone offset number. For instance, EST (eastern time) is -5, since it is 5 hours behind UTC.
  2. Account for daylight savings time (UTC does not change for daylight savings). If it is daylight savings time, and you add an hour for daylight savings time, add an hour to the offset number. -5 becomes -4 because (-5 + 1 = -4). Because you set the clocks an hour ahead for daylight savings time, your time is one less hour offset from UTC.
  3. Calculate the difference between your local time zone offset and the time zone offset you want to convert. Remember you are adding positive and negative numbers. Example: Converting 12:01 UTC +2 to your time zone, UTC -4. Calculation: +2 – (-4) = 6. The difference is 6 hours between your time zone (UTC -5) and UTC +2.
  4. Add or subtract the difference in #3 to the time in the time zone you wanted to convert using your -/+ symbol. If your time zone is -UTC, and the other is +UTC, subtract the difference. If your time zone was +UTC and the other was -UTC add the difference. In the example the time was 12:01+UTC and your time zone is -UTC, so it is 12:01 – 6 = 6:01 AM.
  5. Convert to military time if necessary. 6:01 Am would simply be 0600. However if your answer were 2:00 PM, change it to 1400.

You can do the military time conversion before your calculation and simply skip the conversion into 12-hr format. If the time is 1400 UTC + 2. Find the difference in your time zone and the converting time zone. I.E. +2 – (-4) = 6. Change the 6 to 0600 hours, and subtract: 1400 – 0600 = 0800 hours.

When adding or subtracting negative numbers always pay attention to the real values. Remember that adding a negative is really subtracting that value from it.

10 – (-4) = 14, not 6. Because you are taking away a negative. Removing a negative is really adding that value.

By the same math, -4 + 10 = 6, not 14 because you are adding 10 to a negative, or adding to a deficit. -4 + 10 is really the same as saying 10 – 4.

Hint: Think of the numbers on a scale with 0 in the middle and negative numbers ascending to the left.

Brian lives in Australia and needs to convert a UTC time into his local time. Problem is, he doesn't know how to go about doing it.

UTC is an abbreviation for Coordinated Universal Time. (Yes, I know it looks like the abbreviation letters are out of order. They are; this is why it isn't an acronym. The abbreviation is—believe it or not—based on a political compromise.) UTC is equivalent to International Atomic Time with leap seconds added at irregular intervals to compensate for the Earth's slowing rotation. UTC is never out of synch with GMT (Greenwich Meridian Time) by more than nine tenths of a second, so the two (UTC and GMT) are virtually equivalent in common usage.


Because of this, all you need to do to convert from UTC to a local time is to figure out how many hours your time varies from GMT. There are any number of Websites you can visit to determine such information; the following is an example of one you can use. (Just click a city near you that you know is on the same time zone as you, then look at the resulting time to see how many hours different you are from GMT.)

If you are near Sydney, Australia, you can see that your local time is ten hours ahead of GMT. This means that to determine the local time if you know UTC, all you need to do is add ten hours to that time. If the UTC is in cell B3 in Excel's date and time format, then you could use either of these formulas:

You should understand that these formulas don't account of Daylight Savings Time. If you live in an area that implements some sort of time adjustment scheme (such as DST), then you will need to adjust your formulas accordingly. This means that if you are near Sydney you need to figure out when DST starts and ends, and if you are currently affected by DST you will need to add eleven hours to your UTC value.
