Standard Timestamp Format
Timestamps used in database import scripts and files are always rendered in ISO 8601 format. This creates timestamps in the form, 2010-10-21T17:01:22Z
for a date with time and 2010-10-21
for just a date.
There are several benefits to this format:
- MS Excel won't mangle it;
- It sorts correctly;
- The fields are unambiguous;
- It is easy to parse with Python or R.
All timestamps are converted into UTC from the original local time.
