In addition to time zones, you can customize the timestamps in the deliverables sent to your customers.

You can define a default date and time format in the Settings section of the dashboard. It is also possible to override the default timestamp format for individual envelopes by setting the timestamp_format parameter when creating the envelope.

To define the timestamp format, you use the following tokens:

TokenDescription
YYYYYear
MMMonth
DDDay
HHHour in 24-hour format
hhHour in 12-hour format
mmMinutes
ssSeconds

For separators, you can use the following options for dates: / (slash), - (dash), . (period), (space), and the following for time: : (colon), . (period).

These examples are valid timestamp_format values:
